Essay 116. Describe the structure of the blood-brain barrier and explain why it is important.

TOPICS: 1.2 The Nerve Impulse 118. Describe how the brain transports essential chemicals.

ANSWER: The brain has several transport mechanisms. Small, uncharged molecules, including oxygen and carbon dioxide, cross freely. Water crosses through special protein channels in the wall of the endothelial cells. Also, molecules that dissolve in the fats of the membrane cross easily. Examples include vitamins A and D and all the drugs that affect the brain—from antidepressants and other psychiatric drugs to illegal drugs such as heroin. How fast a drug takes effect depends partly on how readily it dissolves in fats and therefore crosses the blood– brain barrier.

For a few other chemicals, the brain uses active transport, a protein-mediated process that expends energy to pump chemicals from the blood into the brain. Chemicals that are actively transported into the brain include glucose (the brain’s main fuel), amino acids (the building blocks of proteins), purines, choline, a few vitamins, iron, and certain hormones.

TOPICS: 1.1 The Cells of the Nervous System 119. Describe the key aspects of the resting potential.

ANSWER: All parts of a neuron are covered by a membrane about 8 nanometers (nm) thick (just less than 0.00001 mm), composed of two layers (free to float relative to each other) of phospholipid molecules (containing chains of fatty acids and a phosphate group). Embedded among the phospholipids are cylindrical protein molecules through which various chemicals can pass. The structure of the membrane and its proteins controls the flow of chemicals between the inside and outside of the cell. When at rest, the membrane maintains an electrical gradient, also known as polarization—a difference in electrical charge between the inside and outside of the cell. The neuron inside the membrane has a slightly negative electrical

potential with respect to the outside, mainly because of negatively charged proteins inside the cell. This difference in voltage is called the resting potential.

TOPICS: 1.2 The Nerve Impulse 120. Explain the function and process of a neuron’s refractory period.

ANSWER: Although the electrical potential across the membrane is returning from its peak toward the resting point, it is still above the threshold. Why doesn’t the cell produce another action potential during this period? (If it did, of course, it would endlessly repeat one action potential after another.) Immediately after an action potential, the cell is in a refractory period during which it resists the production of further action potentials. In the first part of this period, the absolute refractory period, the membrane cannot produce an action potential, regardless of the stimulation. During the second part, the relative refractory period, a stronger-than-usual stimulus is necessary to initiate an action potential. The refractory period depends on two facts: The sodium channels are closed, and potassium is flowing out of the cell at a faster-than-usual rate. In most of the neurons that researchers have tested, the absolute refractory period is about 1 millisecond (ms), and the relative refractory period is another 2 to 4 ms.

TOPICS: 2.2 Chemical Events at the Synapse 118. Briefly describe spatial summation.

ANSWER: Sherrington found that synapses have the property of spatial summation—that is, summation over space. Synaptic inputs from separate locations combine their effects on a neuron.

Sherrington again began with a pinch too weak to elicit a reflex. This time, instead of pinching one point twice, he pinched two points at once. Although neither pinch alone produced a reflex, together they did. Sherrington concluded that pinching two points activated separate sensory neurons, whose axons converged onto one neuron in the spinal cord. Excitation from either sensory axon excited that spinal neuron, but not enough to reach the threshold. A combination of excitations exceeded the threshold and produced an action potential. Again, Eccles confirmed Sherrington’s inference, demonstrating that EPSPs from several axons summate their effects on a postsynaptic cell.

Spatial summation is critical to brain functioning. Sensory input to the brain arrives at synapses that individually produce weak effects. However, each neuron receives many incoming axons that might produce synchronized responses. Spatial summation assures that those synchronized inputs excite a neuron enough to activate it.

2.1 The Concept of the Synapse

119. Describe the main chemical events at a synapse.

ANSWER: Understanding the chemical events at a synapse is fundamental to understanding the nervous system. Every year, researchers discover more and more details about synapses, their structure, and how those structures relate to function. Here are the major events: 1. The neuron synthesizes chemicals that serve as neurotransmitters. It synthesizes the smaller neurotransmitters in the axon terminals and synthesizes neuropeptides in the cell body.

2. Action potentials travel down the axon. At the presynaptic terminal, an action potential enables calcium to enter the cell. Calcium releases neurotransmitters from the terminals and into the synaptic cleft, the space between the presynaptic and postsynaptic neurons.

3. The released molecules diffuse across the cleft, attach to receptors, and alter the activity of the postsynaptic neuron.

4. The neurotransmitter molecules separate from their receptors.

5. The neurotransmitter molecules may be taken back into the presynaptic neuron for recycling or they may diffuse away.

6. Some postsynaptic cells send reverse messages to control the further release of neurotransmitter by presynaptic cells.

TOPICS: 2.2 Chemical Events at the Synapse 120. Describe the main properties of neuropeptides (neuromodulators).

ANSWER: Researchers often refer to the neuropeptides as neuromodulators, because they have several Synapses 111 properties that set them apart from other transmitters. Whereas the neuron synthesizes most other neurotransmitters in the presynaptic terminal, it synthesizes neuropeptides in the cell body and then slowly transports them to other parts of the cell.

Whereas other neurotransmitters are released at the axon terminal, the neuropeptides are released mainly by dendrites, and also by the cell body and the sides of the axon. A single action potential can release other neurotransmitters, but neuropeptide release requires repeated stimulation. However, after a few dendrites release a neuropeptide, the released chemical primes other nearby dendrites to release the same neuropeptide also, including dendrites of other cells. Thus, neurons containing neuropeptides do not release them often, but when they do, they release substantial amounts. Furthermore, unlike other transmitters that are released immediately adjacent to their receptors, neuropeptides diffuse widely, slowly affecting many neurons in their region of the brain. In that way they resemble hormones. Because many of them exert their effects by altering gene activity, their effects are long-lasting, in the range of 20 minutes or more. Neuropeptides are important for hunger, thirst, and other long-term changes in behavior and experience.

TOPICS: 3.3 Research Methods 118. Describe the basic anatomy and function of the spinal cord.

ANSWER: The spinal cord is the part of the CNS within the spinal column. The spinal cord communicates with all the sense organs and muscles except those of the head. It is a segmented structure, and each segment has on each side a sensory nerve and a motor nerve.

One of the first discoveries about the functions of the nervous system was that the entering dorsal roots (axon bundles) carry sensory information, and the exiting ventral roots carry motor information. The cell bodies of the sensory neurons are in clusters of neurons outside the spinal cord, called the dorsal root ganglia. Cell bodies of the motor neurons are inside the spinal cord. In the cross-section through the spinal cord, the H-shaped gray matter in the center of the cord is densely packed with cell bodies and dendrites. Many neurons from the gray matter of the spinal cord send axons to the brain or to other parts of the spinal cord through the white matter, containing myelinated axons. Each segment of the spinal cord sends sensory information to the brain and receives motor commands from the brain. All that information passes through tracts of axons in the spinal cord. If the spinal cord is cut at a given segment, the brain loses sensation from that segment and below. The brain also loses motor control over all parts of the body served by that segment and the lower ones.

DIFFICULTY: Bloom’s: Analyze REFERENCES: The Spinal Cord LEARNING OBJECTIVES: KALA.BIOP.16.03.02 - Describe the principal functions of certain brain areas.

TOPICS: 3.1 Structure of the Vertebrate Nervous System 119. Describe the basic functions and components of the autonomic nervous system.

ANSWER: The autonomic nervous system consists of neurons that receive information from and send commands to the heart, intestines, and other organs. Its two parts are the sympathetic and parasympathetic nervous systems. The sympathetic nervous system, a network of nerves that prepare the organs for vigorous activity, consists of chains of ganglia just to the left and right of the spinal cord’s central regions (the thoracic and lumbar areas). These ganglia are connected by axons to the spinal cord. Sympathetic axons prepare the organs for “fight or flight”— increasing breathing and heart rate and decreasing digestive activity. Because the sympathetic ganglia are closely linked, they often act as a single system “in sympathy” with one another, although an event may activate some parts more than others. The sweat glands, the adrenal glands, the muscles that constrict blood vessels, and the muscles that erect the

hairs of the skin have sympathetic input but no parasympathetic input.

The parasympathetic nervous system facilitates vegetative, nonemergency responses. The term para means “beside” or “related to,” and parasympathetic activities are related to, and generally the opposite of, sympathetic activities. For example, the sympathetic nervous system increases heart rate, but the parasympathetic nervous system decreases it. The parasympathetic nervous system increases digestive activity, whereas the sympathetic nervous system decreases it. The parasympathetic system also promotes sexual arousal, including erection in males. Although the sympathetic and parasympathetic systems produce contrary effects, both are constantly active to varying degrees, and many stimuli arouse parts of both systems.

ANSWER: b DIFFICULTY: Difficult Essay 119. Define proliferation during neural development.

ANSWER: Proliferation involves the production of new cells. Early in development, the cells lining the ventricles of the brain divide. Some cells remain where they are, continuing to divide.

Others become primitive neurons and glia that begin migrating to other locations.

TOPICS: 4.2 Development of the Brain 120. Describe how phantom limb sensations that seemingly come from a missing hand might occur when the face is touched.

ANSWER: The area of the cortex that normally responds to the face can send collateral sprouts to the adjacent area of the cortex that was innervated by the hand. Investigators recorded from the cerebral cortices of monkeys whose sensory nerves from one forelimb had been cut 12 years previously. They found that the stretch of cortex previously responsive to the limb was now responsive to the face (Pons et al., 1991). After loss of sensory input from the forelimb, the axons representing the forelimb degenerated, leaving vacant synaptic sites at several levels of the CNS. Evidently, axons representing the face sprouted into those sites in the spinal cord, brain stem, and thalamus (Florence & Kaas, 1995; E. G. Jones & Pons, 1998). Or perhaps axons from the face were already present but became stronger through denervation supersensitivity. Brain scan studies confirm that the same processes occur with humans. Later studies showed that this process can be much quicker than 12 years DIFFICULTY: Bloom’s: Analyze REFERENCES: Later Mechanisms of Recovery LEARNING OBJECTIVES: KALA.BIOP.16.04.010 - Explain how remodeling in the cerebral cortex produces the phantom limb experience.

121. Describe Lamarckian evolution and the evidence for or against it.

ANSWER: You may have heard people say something like, “Because we hardly ever use our little toes, they get smaller and smaller in each succeeding generation.” This idea is a carryover of biologist Jean- Baptiste Lamarck’s theory of evolution through the inheritance of acquired characteristics, known as Lamarckian evolution. According to this idea, if you exercise your arm muscles, your children will be born with bigger arm muscles, and if you fail to use your little toes, your children’s little toes will be smaller than yours. However, biologists have found no mechanism for Lamarckian evolution to occur and no evidence that it does. Using or failing to use some body structure does not change the genes. People’s little toes will shrink in future generations only if people with genes for smaller little toes manage to reproduce more than other people do.

TOPICS: 4.1 Genetics and Evolution of Behavior 122. How is brain development related to adolescent impulsivity?

ANSWER: Adolescents are widely regarded as impulsive and prone to seek immediate pleasure, as compared to adults. Impulsiveness is a problem if it leads to risky driving, drinking, sex, spending sprees, and so forth.

Many studies have found that adolescent humans show stronger brain responses than older adults do when anticipating rewards, and weaker responses in the areas of the prefrontal cortex responsible for inhibiting behaviors. That type of evidence influenced the U.S. Supreme Court to rule that adolescents are less responsible for their actions than adults are, because they are less able to restrain their impulses. However, although the prefrontal cortex is indeed less mature in adolescents, its immaturity is at best only part of the explanation for impulsivity. Adolescents are not incapable of restraining their impulses, and in many laboratory tests they inhibit impulses just as well as adults. The heightened impulsivity occurs almost entirely in social situations when adolescents are trying to impress their peers.

Adolescents are highly responsive to social support and social influence.

TOPICS: 4.2 Development of the Brain 123. Describe the relationship between heredity and environment.

ANSWER: Suppose someone asks whether singing ability depends on heredity or environment. That question as stated is meaningless. Unless you had both heredity and environment, you couldn’t sing at all. However, we can rephrase the question meaningfully: Do the observed differences among individuals depend more on differences in heredity or differences in environment? For example, if you sin better than someone else, the reason could be different genes, better training, or both. If the variations in some characteristic depend largely on genetic differences, the characteristic has high heritability.

To determine the heritability of any characteristic, researchers rely mainly on three kinds of evidence. First, they compare monozygotic (“from one egg”) twins and dizygotic (“from two ggs”) twins. People usually call monozygotic twins “identical” twins, but that term is misleading, because identical twins often differ in important ways. Some are mirror images of each other. Also, for epigenetic reasons, certain genes may be activated more in one twin than the other. Still, they have the same genes, whereas dizygotic twins do not. A stronger resemblance between monozygotic than dizygotic twins suggests a genetic contribution.

However, it is not totally decisive, because people who look alike tend to be treated alike.

A second kind of evidence is studies of adopted children. Any tendency for adopted children to resemble their biological parents suggests a hereditary influence. However, again the evidence is not always decisive. The biological mother contributes not only her genes, but also the prenatalnvironment. A mother’s health, diet, and smoking and drinking habits during pregnancy can greatly influence her child’s development, especially the brain development.

A similarity between an adopted child and the genetic mother could reflect both genetic influences and prenatal environment.

A third type of evidence is to identify specific genes linked to some behavior. In some cases, researchers test a hypothesis, such as “a gene that decreases the activity of the serotonin transporter may be linked to an increased risk of depression.” In other cases, they examine all the genes of people with some condition (such as depression or schizophrenia), looking for any gene that is more common than in the rest of the population. However, this procedure tests thousands of hypotheses at once (one for each gene), and risks reporting a false association. Even a trait with high heritability can be modified by environ- mental interventions. A prime example is phenylketonuria, or PKU, a genetic in- ability to metabolize the amino acid phenylalanine. If PKU is not treated, phenylalanine accumulates to toxic levels, impairing brain development and leaving a child mentally retarded, restless, and irritable. Approximately one percent of Europeans carry a recessive gene for PKU. Fewer Asians and almost no Africans have the gene.

Although PKU is a hereditary condition, environmental interventions can modify it.

Physicians in many countries routinely test the level of phenylalanine or its metabolites in babies’ blood or urine. If a baby has high levels, indicating PKU, physicians advise the parents to put the baby on a trict low-phenylalanine diet to protect the brain. The success of this diet shows that heritable does not mean unmodifiable.

TOPICS: 5.1 Visual Coding 117. What is prosopagnosia?

ANSWER: People with severe problems, either because of brain damage or because they developed fewer connections, may have prosopagnosia, meaning an impaired ability to recognize faces.

People with prosopagnosia can read, so visual acuity is not the problem. They recognize people’s voices, so their problem is not memory (Farah, Wilson, Dain, & Tanaka, 1998). Furthermore, if they feel clay models of faces, they are worse than other people at determining whether two clay models are the same or different (Kilgour, de Gelder, & Lederman, 2004). Their problem is not vision in general, but something that relates specifically to faces.

TOPICS: 5.3 Parallel Processing in the Visual Cortex 118. Describe the functional and anatomic differences between rods and cones.

ANSWER: Rods, abundant in the periphery of the human retina, respond to faint light but are not useful in daylight because bright light bleaches them. Cones, abundant in and near the fovea, are less active in dim light, more useful in bright light, and essential for color vision. Because of the distribution of rods and cones, you have good color vision in the fovea but not in the periphery.

(Parvocellular means “small celled,” from the Latin root parv, meaning “small.”) The magnocellular neurons, with larger cell bodies and receptive fields, are distributed evenly throughout the retina. (Magnocellular means “large celled,” from the Latin root magn, meaning “large.” The same root appears in magnify.)

TOPICS: 5.2 How the Brain Processes Visual Information 120. Describe the key functions of the major pathways in the visual cortex.

ANSWER: The primary visual cortex (V1) sends information to the secondary visual cortex (area V2), which processes the information further and transmits it to additional areas. The connections in the visual cortex are reciprocal. For example, V1 sends information to V2, and V2 returns information to V1.

From V2, the information branches out in several directions for specialized processing. Researchers distinguish between the ventral stream and the dorsal stream. They call the ventral stream through the temporal cortex the “what” pathway, because it is specialized for identifying and recognizing objects. The dorsal stream through the parietal cortex, once called the “where” pathway, is now called the “how” pathway, because of its importance for visually guided movements.

Although the distinction between ventral and dorsal pathways is useful, we should not overstate it.

Normal behavior makes use of both pathways in collaboration (Farivar, 2009), and although damage to either pathway impairs some tasks more than others, it affects all tasks to some degree.

TOPICS: 7.3 The Chemical Senses Essay 116. Describe how the auditory cortex parallels the visual cortex.

ANSWER: The organization of the auditory cortex strongly parallels that of the visual cortex. For example, just as the visual system has a “what” pathway and a “where” pathway, the auditory system has a “what” pathway sensitive to patterns of sound in the anterior temporal cortex, and a “where” pathway sensitive to sound location in the posterior temporal cortex and the parietal cortex. Just as patients with damage in area MT become motion blind, patients with damage in parts of the superior temporal cortex become motion deaf. They hear sounds, but they do not detect that a source of a sound is moving.

Just as the visual cortex is active during visual imagery, area A1 responds to imagined sounds as well as real ones. It becomes active when people view short silent videos that suggest sound—such as someone playing a piano, or a glass vase shattering on the ground. In one study, people listened to several familiar and unfamiliar songs. At various points, parts of each song were replaced by 3- to 5-second gaps. When people were listening to familiar songs, they reported that they heard “in their heads” the notes or words that belonged in the gaps. That experience was accompanied by activity in area A1. During similar gaps in the unfamiliar songs, they did not hear anything in their heads, and area A1 showed no response.

Also like the visual system, development of the auditory system depends on experience. Just as rearing an animal in the dark impairs visual development, rearing one in constant noise impairs auditory development. (In constant noise, it is difficult to identify and learn about individual sounds.) In people who are deaf from birth, the axons leading from the auditory cortex develop less than in other people.

TOPICS: 7.1 Audition 117. Describe in detail one of the ways of relieving pain.

ANSWER: After pain alerts you to a danger, continuing pain messages are unnecessary. The brain puts the brakes on prolonged pain by opioid mechanisms—systems that respond to opiate drugs and similar chemicals. Candace Pert and Solomon Snyder (1973) discovered that opiates bind to receptors found mostly in the spinal cord and the periaqueductal gray area of the midbrain A placebo is a drug or other procedure with no pharmacological effects. In medical research, an experimental group receives a potentially active treatment and the control group receives a placebo. Placebos have little effect on most medical conditions, but they often relieve pain or depression.

Cannabinoids—chemicals related to marijuana—also block certain kinds of pain. Unlike opiates, cannabinoids act mainly in the periphery of the body rather than the CNS. Researchers found that if they deleted the cannabinoid receptors in the peripheral nervous system of laboratory animals while leaving the receptors intact in the CNS, cannabinoids lost most of their ability to decrease pain.

Another approach uses capsaicin, a chemical in jalapenos and similar peppers that stimulates receptors for heat. Capsaicin rubbed onto a sore shoulder, an arthritic joint, or other painful area produces a temporary burning sensation followed by a longer period of decreased pain.

When applied in high doses, or at lower doses for a prolonged period, capsaicin causes an excessive buildup of calcium in heat receptors, and damages the mitochondria in those receptors, rendering the cell nonfunctional for a substantial time DIFFICULTY: Bloom’s: Understand REFERENCES: Pain LEARNING OBJECTIVES: KALA.BIOP.16.06.04 - Describe methods of relieving pain.

TOPICS: 7.2 The Mechanical Senses 118. Describe the differences between labeled-line and across-fiber pattern chemical coding.

ANSWER: In a system relying on the labeled-line principle, each receptor would respond to a limited range of stimuli, and the meaning would depend entirely on which neurons are active. In a system relying on the across-fiber pattern principle, each receptor responds to a wider range of stimuli, and a given response by a given axon means little except in comparison to what other axons are doing DIFFICULTY: Bloom’s: Understand REFERENCES: Chemical Coding LEARNING OBJECTIVES: KALA.BIOP.16.06.01 - Describe the receptors for hearing, vestibular sensation, the somatic senses, and the chemical senses.

TOPICS: 7.3 The Chemical Senses 119. Describe the basic mechanisms of taste receptors.

ANSWER: The receptors for taste are not true neurons but modified skin cells. Like neurons, taste receptors have excitable membranes and release neurotransmitters to excite neighboring neurons, which in turn transmit information to the brain. Like skin cells, however, taste receptors are gradually sloughed off and replaced, each one lasting about 10 to 14 days.

Mammalian taste receptors are in taste buds located in papillae on the surface of the tongue.

A given papilla may contain up to 10 or more taste buds, and each taste bud contains about 50 receptor cells.

Traditionally, people in Western society have described tastes in terms of sweet, sour, salty, and bitter. However, some tastes defy categorization in terms of these four labels.

The saltiness receptor is simple. Recall that a neuron produces an action potential when sodium ions cross its membrane. A saltiness receptor, which detects the presence of sodium, simply permits sodium ions on the tongue to cross its membrane. Chemicals that prevent sodium from crossing the membrane weaken salty tastes.

Sour receptors detect the presence of acids. Sweetness, bitterness, and umami receptors resemble the metabotropic synapses. After a molecule binds to one of these receptors, it activates a G protein that releases a second messenger within the cell. Each of these receptors releases adenosine triphosphate (ATP) as a neurotransmitter.

Bitter taste used to be a puzzle because bitter substances include a long list of dissimilar chemicals. Their only common factor is that they are to some degree toxic. What receptor could identify such a diverse set of chemicals? The answer is that we have not one bitter receptor but a family of 25 or more. Each responds to a few related compounds. One consequence of having so many bitter receptors is that we detect a great variety of dangerous chemicals. The other is that because each type of bitter receptor is present in small numbers, we don’t detect very low concentrations of bitter substances.

TOPICS: 7.3 The Chemical Senses 120. Briefly describe the behavioral effects of pheromones in humans.

ANSWER: In adult humans, the VNO is tiny and has no receptors. It is vestigial—that is, a leftover from our evolutionary past. Nevertheless, part of the human olfactory mucosa contains receptors that resemble other species’ pheromone receptors.

The behavioral effects of pheromones apparently occur unconsciously. That is, people react to certain chemicals in human skin even when they describe them as odorless. The smell of a sweaty woman increases a man’s testosterone secretions, especially if the woman was near her time of ovulation. This effect is stronger for heterosexual men than for homosexual men.

The smell of a sweaty man produces several effects on women, although we have no evidence of increased sexual arousal. The smell of a sweaty man activates a woman’s hypothalamus, but it does so in men also. It also causes women to increase their release of cortisol, a stress hormone. Evidently a man reacts to a sweaty woman as a sex signal, and a woman reacts to a sweaty man as a potential danger signal.

The best-documented effect of a human pheromone relates to the timing of women’s menstrual cycles. Women who spend much time together find that their menstrual cycles become more synchronized, unless they are taking birth-control pills. To test whether pheromones are responsible for the synchronization, researchers exposed young volunteer women to the underarm secretions of a donor woman. In two studies, most of the women exposed to the secretions became synchronized to the donor’s menstrual cycle.

Another study dealt with the phenomenon that a woman in an intimate relationship with a

man tends to have more regular menstrual periods than women not in an intimate relationship. According to one hypothesis, the man’s pheromones promote this regularity. In the study, young women who were not sexually active were exposed daily to a man’s underarm secretions. Gradually, over 14 weeks, most of these women’s menstrual periods became more regular than before. In short, human body secretions probably do act as pheromones, although the effects are more subtle than in most other mammals.

TOPICS: 7.3 Movement Disorders Essay 116. Describe the areas and major functions of the primary motor cortex (include the relevant areas near to the motor cortex).

ANSWER: Since the pioneering work of Gustav Fritsch and Eduard Hitzig (1870), neuroscientists have known that direct electrical stimulation of the primary motor cortex—the precentral gyrus of the frontal cortex, just anterior to the central sulcus—elicits movements. The motor cortex does not send messages directly to the muscles. Its axons extend to the brainstem and spinal cord, which generate the impulses that control the muscles. In most mammals, these axons connect only to interneurons, which in turn control motor neurons. In humans and other

primates, some axons go directly from the cerebral cortex to motor neurons, presumably giving us greater dexterity. Human movements depend on both the axons to motor neurons and axons to interneurons.

The motor cortex is just anterior to the somatosensory cortex, and the two match up nicely.

That is, the brain area that controls the left hand is near the area that feels the left hand, the area that controls the left foot is near the area that feels the left foot, and so forth. You need to feel a body part to control its movement accurately.

The primary motor cortex is important for making movements, but not for initial planning.

One of the first areas to become active in planning a movement is the posterior parietal cortex which monitors the position of the body relative to the world. The prefrontal cortex and the supplementary motor cortex are also important for planning and organizing a rapid sequence.

The premotor cortex is most active immediately before a movement. It receives information about the target to which the body is directing its movement, as well as information about the body’s current position and posture. The prefrontal cortex, which is also active during a delay before a movement, stores sensory information relevant to a movement. It is also important for considering the probable outcomes of possible movements.

TOPICS: 7.2 Brain Mechanisms of Movement 117. Describe the significance of mirror neurons.

ANSWER: O f discoveries in neuroscience, one of the most exciting to psychologists has been mirror neurons, which are active both during preparation for a movement and while watching someone else perform the same or a similar movement. Mirror neurons were first reported in the premotor cortex of monkeys and later in other areas and other species, including humans.

These neurons are theoretically exciting because of the idea that they may be important for understanding other people, identifying with them, and imitating them. For example, mirror neurons in part of the frontal cortex become active when people smile or see someone else smile, and they respond especially strongly in people who report identifying strongly with other people. Many people have speculated that people with autism—who fail to form strong social bonds—might lack mirror neurons. However, one study using fMRI found normal mirror neuron responses in autistic people, so we need to look elsewhere to explain autism.

Mirror neurons are activated not only by seeing an action, but also by any reminder of the action. Certain cells respond to hearing an action as well as seeing or doing it. Other cells respond to either doing an action or reading about it.

The possibilities are exciting, but before we speculate too far, an important question remains: Do mirror neurons cause imitation and social behavior, or do they result from them? Put another way, are we born with neurons that respond to the sight of a movement and also facilitate the same movement? If so, they could be important for social learning. However, another possibility is that we learn which visible movements correspond to movements of our own. Then seeing others’ actions reminds us of our own, and activates brain areas responsible for those actions. In that case, mirror neurons are not responsible for imitation or socialization.

The answer may be different for different movements. Some newborn infants imitate a few facial movements, especially tongue protrusion. That result implies built-in mirror neurons that connect the sight of a movement to the movement itself. However, in both monkey and human infants, many mirror neurons do not respond to observations of others’ movements

until after the infant has practiced making those movements itself. A mirror neuron cannot be essential for learning to imitate a movement if you have to practice the movement before that neuron develops its mirror properties.

Also, researchers identified mirror neurons that responded both when people moved a certain finger, such as the index finger, and when they watched someone else move the same finger.

Then they asked people to watch a display on the screen and move their index finger whenever the hand on the screen moved the little finger. They were to move their little finger whenever the hand on the screen moved the index finger. After some practice, these “mirror” neurons turned into “counter-mirror” neurons that responded to movements of one finger by that person and the sight of a different finger on the screen. In other words, at least some mirror neurons modify their properties by learning, and therefore it is possible that they developed their original properties by learning also.

TOPICS: 7.2 Brain Mechanisms of Movement 118. Describe the relationship of conscious decisions and movements. What may this relationship reveal about consciousness?

ANSWER: Each of us has the feeling, “I consciously decide to do something, and then I do it.” That sequence seems so obvious that we might not even question it, but research casts doubt on this assumption. Research indicates that the brain activity responsible for the movement apparently began before the person’s conscious decision to move. The results seem to indicate that your conscious decision does not cause your action. Rather, you become conscious of the decision after the process leading to action has already been underway for about 300 ms. None of these results deny that you make a voluntary decision. The implication, however, is that what we identify as a conscious decision is the perception of a gradual brain process. It probably begins with unconscious processes that build up to a certain level before they become conscious.

TOPICS: 7.2 Brain Mechanisms of Movement 119. Briefly describe the cellular organization of the cerebellum.

ANSWER: The cerebellum receives input from the spinal cord, from each of the sensory systems by way of the cranial nerve nuclei, and from the cerebral cortex. That information eventually reaches the cerebellar cortex, the surface of the cerebellum.    

The neurons are arranged in a precise geometrical pattern, with multiple repetitions of the same units.

The Purkinje cells are flat (two-dimensional) cells in sequential planes, parallel to one another.

The parallel fibers are axons parallel to one another and perpendicular to the planes of the Purkinje cells.

Action potentials in parallel fibers excite one Purkinje cell after another. Each Purkinje cell then transmits an inhibitory message to cells in the nuclei of the cerebellum (clusters of cell bodies in the interior of the cerebellum) and the vestibular nuclei in the brainstem, which in turn send information to the midbrain and the thalamus.



Depending on which and how many parallel fibers are active, they might stimulate only the first few Purkinje cells or a long series of them. Because the parallel fibers’ messages reach different Purkinje cells one after another, the greater the number of excited Purkinje cells, the greater their collective duration of response. That is, if the parallel fibers stimulate only the first few Purkinje cells, the result is a brief message to the target cells; if they stimulate more Purkinje cells, the message lasts longer. The output of Purkinje cells controls the timing of a movement, including both its onset and offset.

Briefly describe the nature of Parkinson’s disease. Include a discussion of its causes and possible treatments.

ANSWER: The main symptoms of Parkinson’s disease (also known as Parkinson disease) are rigidity, muscle tremors, slow movements, and difficulty initiating physical and mental activity. It becomes more common as people age, striking 1 percent to 2 percent of people over age 65.

Early symptoms usually include loss of olfaction and psychological depression. Many but not all Parkinson’s patients have cognitive deficits, which may include problems with attention, language, or memory. The immediate cause of Parkinson’s disease is the gradual loss of neurons in the substantia nigra and therefore a loss of dopamine-releasing axons to the striatum (part of the basal ganglia). With the loss of this input, the striatum decreases its inhibition of the globus pallidus, which therefore increases its inhibitory input to the thalamus. The result is less vigorous voluntary movements. People with Parkinson’s disease are still capable of movement, and sometimes they move normally in response to signals or instructions, such as when following a parade. However, their spontaneous movements are slow and weak.

What causes the damage to the substantia nigra? An early study reported that having a monozygotic twin with early-onset Parkinson’s disease greatly increased your probability of getting it, but having a monozygotic twin with late-onset disease had no effect. That result implied that genes make little or no contribution to late-onset Parkinson’s disease. Later studies have found less extreme results, indicating that genes do influence the late-onset disease, though less strongly than they impact early-onset disease. So far, researchers have identified more than 20 genes that apparently increase the risk of Parkinson’s disease, although the results vary from one study to another, and one population to another.

The results agree, however, that none of these genes by itself produces a high risk. An accidental discovery implicated exposure to toxins as another factor in Parkinson’s disease.

In northern California in 1982, several young adults developed symptoms of Parkinson’s disease after using a drug similar to heroin. Before the investigators could alert the community to the danger, many other users had developed symptoms ranging from mild to fatal. The substance responsible for the symptoms was MPTP, a chemical that the body converts to MPP+, which accumulates in, and then destroys, neurons that release dopamine, partly by impairing the transport of mitochondria from the cell body to the synapse.

Postsynaptic neurons react to the loss of input by increasing their number of dopamine receptors.

People are sometimes exposed to hazardous environmental chemicals that damage cells of the substantia nigra. Many studies have shown increased risk of Parkinson’s disease among people with much exposure to insecticides, herbicides, and fungicides, including paraquat, rotenone, maneb, and ziram. The disease is more common in farmers and other rural dwellers

than in city dwellers, presumably because of increased exposure to these chemicals. Exposure to these chemicals increases the risk especially among people with any of the genes that predispose to Parkinson’s. If someone also had a traumatic head injury, the risk goes up even more. In short, most cases result from several influences combined, not just one.

What else might influence the risk of Parkinson’s disease? Researchers compared the lifestyles of people who did and didn’t develop the disease. One factor that stands out consistently is cigarette smoking and coffee drinking: People who smoke cigarettes or drink coffee have less chance of developing Parkinson’s disease.

Because Parkinson’s disease results from a dopamine deficiency, a logical goal is to restore the missing dopamine. A dopamine pill would be ineffective because dopamine does not cross the blood–brain barrier. Physicians in the 1950s and 1960s reasoned that L-dopa, a precursor to dopamine that does cross the barrier, might be a good treatment. In contrast to all the medicines that were discovered by trial and error, this was the first drug in psychiatry or neurology, and one of the first in all of medicine, to emerge from a plausible theory. Taken as a daily pill, L-dopa reaches the brain, where neurons convert it to dopamine. L-dopa is still the most common treatment for Parkinson’s disease. However, L-dopa treatment is disappointing in several ways. It increases dopamine release in all axons, including those that had deteriorated and those that were still functioning normally. It produces spurts of high release alternating with lower release. Even if it adequately replaces lost dopamine, it does not replace other transmitters that are also depleted. It does not slow the continuing loss of neurons. And it produces unpleasant side effects such as nausea, restlessness, sleep problems, low blood pressure, repetitive movements, and sometimes hallucinations and delusions.

A potentially exciting strategy has been “in the experimental stage” since the 1980s. In a pioneering study, M. J. Perlow and colleagues (1979) injected the chemical 6-OHDA (6hydroxydopamine, a chemical modification of dopamine) into rats to damage the substantia nigra of one hemisphere, producing Parkinson’s-type symptoms on the opposite side of the body. After the movement abnormalities stabilized, the experimenters transplanted substantia nigra tissue from rat fetuses into the damaged brains. Most recipients recovered much of their normal movement within four weeks. Control animals that suffered the same brain damage without receiving grafts showed little or no recovery. This is only a partial brain transplant, but still, the Frankensteinian implications are striking.

If such surgery works for rats, might it also for humans? Ordinarily, scientists test any experimental procedure extensively with laboratory animals before trying it on humans, but with Parkinson’s disease, the temptation was too great. People in the late stages have little to lose and are willing to try almost anything. The obvious problem is where to get the donor tissue. Several early studies used tissue from the patient’s own adrenal gland. Although that tissue is not composed of neurons, it produces and releases dopamine. Unfortunately, the adrenal gland transplants seldom produced much benefit.

Another possibility is to transplant brain tissue from aborted fetuses. Fetal neurons transplanted into the brains of patients with Parkinson’s sometimes survive for years and make synapses with the patient’s own cells. However, the operation is expensive and difficult, requiring brain tissue from four to eight aborted fetuses, and the benefits to the patient have been small at best.

DIFFICULTY: REFERENCES:

A related approach is to take stem cells—immature cells that are capable of differentiating into other cell types—guide their development so that they produce large quantities of Ldopa, and then transplant them into the brain. The idea sounds promising, but researchers will need to overcome several difficulties before this might become an effective treatment.

Essay 116. Briefly describe the role of the locus coeruleus in arousal and attention.

ANSWER: The locus coeruleus is a small structure in the pons which is inactive at most times but emits bursts of impulses in response to meaningful events. Axons from the locus coeruleus release norepinephrine widely throughout the cortex, so this area has a huge influence. Anything that stimulates the locus coeruleus strengthens the storage of recent memories and increases wakefulness. The locus coeruleus is silent during sleep.

TOPICS: 8.2 Stages of Sleep and Brain Mechanisms 117. Describe how light resets the SCN. ANSWER: Although cells throughout the body generate circadian rhythms, the main driver of rhythms for sleep and body temperature is the suprachiasmatic nucleus, or SCN, a part of the hypothalamus. After damage to the SCN, the body’s rhythms become erratic.

A small branch of the optic nerve, known as the retinohypothalamic path, from the retina to the SCN, alters the SCN’s settings. Most of the input to that path, however, does not come from normal retinal receptors. Mice with genetic defects that destroy nearly all their rods and cones nevertheless reset their biological clocks in synchrony with the light. Also, consider blind mole rats, whose eyes are covered with folds of skin and fur. They are evolutionarily adapted to spend most of their lives underground. They have fewer than 900 optic nerve axons compared with 100,000 in hamsters. Even a bright flash of light evokes no startle response and no measurable change in brain activity. Nevertheless, light resets their circadian rhythms, enabling them to be awake only at night.

The surprising explanation is that the retinohypothalamic path to the SCN comes from a special population of retinal ganglion cells that have their own photopigment, called melanopsin, unlike the ones found in rods and cones. These special ganglion cells receive

some input from rods and cones, but even if they do not receive that input, they respond directly to light. These special ganglion cells are located mainly near the nose, from which they see toward the periphery. They respond to light slowly and turn off slowly when the light ceases. Therefore, they respond to the overall average amount of light, not to instantaneous changes in light. The average intensity over a period of time is, of course, exactly the information the SCN needs to gauge the time of day. These ganglion cells respond mainly to short-wavelength (blue) light.

Note several consequences: First, some people who are blind because of damage to the rods and cones, or by damage to the visual cortex, nevertheless have enough input to the melanopsin-containing ganglion cells to entrain their waking and sleeping cycle to the local pattern of sunlight. Second, it was formerly puzzling that bright light aggravates migraine headaches for many blind people. The explanation is that the melanopsin-containing ganglion cells send input to the posterior thalamus, which is part of the pathway producing pain in migraines. Someone with no input to the visual cortex, and therefore no conscious vision, can nevertheless have light-sensitive excitation in the thalamus. A third consequence: Because these ganglion cells respond strongly to short-wavelength light, exposure to such light late in the day tends to reset the circadian rhythm, phase-delaying it. Computers, cell phones, and televisions emit a high percentage of short-wavelength light. Therefore, people who use those media in the evenings are likely to have trouble falling asleep, and further trouble awakening at the intended time the next morning.

TOPICS: 8.2 Stages of Sleep and Brain Mechanisms 118. Describe brain function during REM sleep.

ANSWER: During REM sleep, activity increased in the pons (which triggers the onset of REM sleep) and the limbic system (which is important for emotional responses). Activity decreased in the primary visual cortex, the motor cortex, and the dorsolateral prefrontal cortex but increased in parts of the parietal and temporal cortex. REM sleep is associated with a distinctive pattern of high-amplitude electrical potentials known as PGO waves, for pons-geniculate-occipital.

Waves of neural activity are detected first in the pons, shortly afterward in the lateral geniculate nucleus of the thalamus, and then in the occipital cortex.

REM sleep apparently depends on a relationship between the neurotransmitters serotonin and acetylcholine. Injections of the drug carbachol, which stimulates acetylcholine synapses, quickly move a sleeper into REM sleep. Note that acetylcholine is important for both wakefulness and REM sleep, states of brain arousal. Serotonin and norepinephrine interrupt REM sleep.

TOPICS: 8.2 Stages of Sleep and Brain Mechanisms 119. Discuss the relationship between sleep and memory.

ANSWER: Young adults deprived of a night’s sleep show deficits on memory tasks. In contrast, if people learn something and then go to sleep, or even take a nap, their memory often becomes better than it was before the sleep. That is, we see not just an absence of forgetting but also a gain of memory. The amount of improvement varies from one study to another and from one type of learning task to another. Still, reviewing something right before you go to sleep is a helpful strategy. In one study, people viewed 50 objects making a sound (such as a cat meowing) in various locations on a computer screen. Then they took a nap, during which

they heard some of those sounds again. After the nap, they were tested on their memory for the location of each object on the screen. They showed enhanced memory for the objects whose sounds they heard during the nap. Evidently the sounds reminded them of the information, and the brain then processed that information again.

Sleep also helps people reanalyze their memories: In one study, people who had just practiced a complex task were more likely to perceive a hidden rule (an “aha” experience) after a period of sleep than after a similar period of wakefulness. Another study found that a nap that included REM sleep enhanced performance on certain kinds of creative problem solving. However, an afternoon nap also leaves someone less alert than usual for the next half hour.

How does sleep enhance memory? Researchers recorded activity in the hippocampus during learning, and then recorded from the same locations during sleep, using microelectrodes within cells for laboratory animals and electrodes on the scalp for humans. The results: Patterns that occurred during sleep resembled those that occurred during learning, except that they were more rapid during sleep. Furthermore, the amount of hippocampal activity during sleep correlated highly with the subsequent improvement in performance. These results suggest that the brain replays its daily experiences during sleep. However, further research found that the sleeping brain replays its experience backward as often as forward, and that it sometimes replays less common experiences more often than more common ones. Also, the hippocampus replays recently learned patterns during quiet waking periods, not just during sleep. So the role of hippocampal replay during sleep is less clear than it once appeared to be.

One way for sleep to strengthen memory is by weeding out the less successful connections.

Suppose that every time you learn something, your brain strengthened certain synapses without making adjustments elsewhere. As you learned more and more, you would have more and more brain activity. By middle age, your brain might be burning with constant activity. To prevent runaway overactivity, your brain compensates for strengthening some synapses by weakening or removing others, mostly during sleep. Weakening less appropriate synapses emphasizes the ones that were strengthened during wakefulness.

Another aspect of sleep’s contribution to memory relates to sleep spindles. Recall that sleep spindles are waves of activity, about 12 to 14 Hz, that are particularly common during stage 2 sleep. They indicate an exchange of information between the thalamus and cerebral cortex.

Sleep spindles increase in number after new learning, and the number of sleep spindles correlates positively with improvements in certain types of memory.

120. Discuss the leading theories on the biological perspectives on dreaming.

ANSWER: According to the activation-synthesis hypothesis, a dream represents the brain’s effort to make sense of sparse and distorted information. Dreams begin with periodic bursts of spontaneous activity in the pons—the PGO waves—that activate some parts of the cortex but not others. The cortex combines this haphazard input with whatever other activity was already occurring and does its best to synthesize a story that makes sense of the information.

An alternative view of dreams has been labeled the clinico-anatomical hypothesis because it was derived from clinical studies of patients with various kinds of brain damage. Like the activation-synthesis theory, this theory emphasizes that dreams begin with arousing stimuli that are generated within the brain combined with recent memories and any information the brain is receiving from the senses. However, the clinico-anatomical hypothesis puts less

emphasis on the pons, PGO waves, or REM sleep. It regards dreams as thinking that takes place under unusual conditions.

Essay 116. Describe the different causes and mechanisms of osmotic thirst.

ANSWER: Osmotic thirst is caused by an increased concentration of solutes in the extracellular fluid, either by increased salt intake, or water loss. Osmotic thirst is detected by neurons in the OVLT that cause increased release of vasopressin (which decreases urine output and raises blood pressure) and increased activity in the LPO to initiate drinking, preferably of pure water.

TOPICS: 9.2 Thirst 117. How does cholecystokinin limit meal size?

ANSWER: Cholecystokinin constricts the sphincter muscle between the stomach and duodenum, causing the stomach to hold its contents and fill more quickly than usual. It also stimulates the vagus nerve to send signals to the hypothalamus, causing cells there to release a neurotransmitter that is a shorter version of the cholecystokinin molecule itself.

TOPICS: 9.3 Hunger 118. Describe the brain mechanisms involved in shivering, sweating, and changes in blood flow to the skin.

ANSWER: The physiological changes that regulate body temperature— such as shivering, sweating, and changes in blood flow to the skin—depend on areas in and near the hypothalamus, especially the anterior hypothalamus and the preoptic area, located just anterior to the anterior hypothalamus. Because of the close relationship between the preoptic area and the anterior hypothalamus, researchers often treat them as a single area, the preoptic area/anterior hypothalamus, or POA/AH. The POA/AH and a couple other hypothalamic areas send output to the hindbrain’s raphe nucleus, which controls the physiological mechanisms such as shivering, sweating, changes in heart rate and metabolism, and changes in blood flow to the skin.

The POA/AH integrates several types of information. It receives input from temperature receptors in the skin, in the organs, and in the brain especially in the POA/AH itself. If the brain or the skin is hot, an animal sweats or pants vigorously and seeks a cooler location. If either is cold, the animal shivers and seeks a warmer location. The animal reacts most vigorously if the brain and skin are both hot or both cold. The POA/AH also receives input from the immune system, which reacts to an infection by steps that deliver prostaglandins and histamines to the POA/AH. The delivery of those chemicals is what causes shivering, increased metabolism, and other processes that produce a fever. People lacking the appropriate receptors for those chemicals fail to develop a fever, even when they have pneumonia or similar diseases.

The POA/AH is not the only brain area that detects temperature, but it is the primary area for controlling physiological mechanisms of temperature regulation such as sweating or shivering. After damage to the POA/AH, mammals can still regulate body temperature, but only by the same behavioral mechanisms that a lizard might use, such as seeking a warmer or colder location.

DIFFICULTY: Bloom’s: Analyze REFERENCES: Controlling Body Temperature LEARNING OBJECTIVES: KALA.BIOP.16.09.01 - List examples of how temperature regulation contributes to behaviors.

TOPICS: 9.1 Temperature Regulation 119. Describe the major brain mechanisms of eating and hunger.

ANSWER: The arcuate nucleus of the hypothalamus has one set of neurons sensitive to hunger signals and a second set sensitive to satiety signals. Damage to one set or the other can lead to starvation or excessive eating. The hunger-sensitive cells receive excitatory input from the taste pathway and from axons releasing the neurotransmitter ghrelin. The stomach releases ghrelin during a period of food deprivation, where it triggers stomach contractions. Ghrelin also acts on the hypothalamus to increase appetite.

Much of the output from the arcuate nucleus goes to the paraventricular nucleus of the hypothalamus. The paraventricular nucleus (PVN) inhibits the lateral hypothalamus, an area important for eating. The hunger cells in the arcuate nucleus inhibit the paraventricular nucleus and the paraventricular nucleus inhibits the lateral hypothalamus. The inhibitory transmitters here are a combination of GABA, neuropeptide Y (NPY), and agouti-related peptide (AgRP).

Axons from the satiety-sensitive cells of the arcuate nucleus deliver an excitatory message to the paraventricular nucleus, releasing melanocortins. Melanocortin receptors in the paraventricular nucleus are important for limiting food intake, and anything that damages these receptors leads to overeating.

The amygdala and related areas send two kinds of input to the lateral hypothalamus. One path inhibits eating during illness and mediates aversion to foods previously associated with illness. The other path stimulates eating in response to highly tasty foods.

An additional pathway from the paraventricular nucleus leads to cells in the lateral hypothalamus that release orexin. Orexin has two roles in feeding. First, it increases animals’ persistence in seeking food. Second, orexin responds to incentives in general. If orexin receptors are blocked, an animal becomes less active and less likely to work for reinforcement of any kind.

Output from the paraventricular nucleus acts on the lateral hypothalamus. The lateral hypothalamus controls insulin secretion, alters taste responsiveness, and facilitates feeding in other ways. The lateral hypothalamus contributes to feeding in several ways: 

  

Axons from the lateral hypothalamus to the NTS (nucleus of the tractus solitarius), part of the taste pathway, alter the taste sensation and the salivation response to the tastes. When the lateral hypothalamus detects hunger, it sends messages that make the food taste better.

Axons from the lateral hypothalamus extend into several parts of the cerebral cortex, facilitating ingestion and swallowing and causing cortical cells to increase their response to the taste, smell, or sight of food.

The lateral hypothalamus increases the pituitary gland’s secretion of hormones that increase insulin secretion.

The lateral hypothalamus sends axons to the spinal cord, controlling autonomic responses such as digestive secretions.

Output from the ventromedial hypothalamus (VMH) inhibits feeding and therefore damage to this nucleus leads to overeating and weight gain. Some people with a tumor in that area have gained more than 10 kg (22 lbs) per month.

TOPICS: 9.3 Hunger 120. Describe how bulimia nervosa resembles drug addiction.

ANSWER: In important ways, bulimia resembles drug addiction. Eating tasty foods activates the same brain areas as addictive drugs, such as the nucleus accumbens. Drug addicts who cannot get drugs sometimes overeat instead, and food-deprived people or animals become more likely than others to use drugs. Researchers examined rats that were food deprived for 12 hours a day, including the first 4 hours of their wakeful period, and then offered a very sweet, syrupy sugar solution. Over several weeks on this regimen, the rats drank more and more each day, especially during the first hour of availability each day. The intake released dopamine and opioid (opiatelike) compounds in the brain, similar to the effects of highly addicting drugs. It also increased the levels of dopamine type 3 receptors in the brain—again, a trend resembling that of rats that receive morphine. If they were then deprived of this sweet liquid, they showed withdrawal symptoms, including head shaking, teeth chattering, and tremors. An injection of morphine relieved these symptoms. In short, the rats showed clear indications of an addiction to big doses of sugar. Similarly, we can regard bulimic cycles of dieting and binge eating as an addiction.

TOPICS: 10.1 Sex and Hormones Essay 116. Describe the organizing effects of sex hormones and give specific examples.

ANSWER: Organizing effects produce long-lasting structural effects. During a sensitive period in early development, the first trimester of pregnancy for humans, sex hormones determine whether the body develops female or male genitals. They lead to more receptors, and therefore greater sensitivity, around the female nipples than the male nipples. Later researchers recognized that sex hormones produce additional organizing effects at puberty. The surge of hormones at puberty produces breast development in women, facial hair and penis growth in men, changes in voice, and male–female differences in the anatomy of certain parts of the hypothalamus. Some of the differences in brain anatomy between males and females increase during this time. The changes developing at puberty persist throughout life, even after the concentration of sex hormones declines.

TOPICS: 10.1 Sex and Hormones 117. Describe activating effects of sex hormones and give specific examples.

ANSWER: Activating effects are more temporary, continuing only while a hormone is present or shortly beyond. For example, current hormone levels influence the degree of sex drive. The burst of hormones during pregnancy produce complex, temporary effects on emotional arousal, aggressive behavior, learning, and cognition.

Testosterone, essential for male sexual arousal, acts partly by increasing touch sensitivity in the penis. Testosterone primes the MPOA and several other brain areas to release dopamine.

MPOA neurons release dopamine strongly during sexual activity, and the more dopamine they release, the more likely the male is to copulate. Levels of testosterone correlate positively with men’s sexual arousal and their drive to seek sexual partners. Decreases in testosterone levels generally decrease male sexual activity. For example, castration (removal of the testes) generally decreases a man’s sexual interest and activity. However, low testosterone is not the usual basis for impotence, the inability to have an erection. The most common cause is impaired blood circulation, especially in older men.

A woman’s hypothalamus and pituitary interact with the ovaries to produce the menstrual cycle, a periodic variation in hormones and fertility over the course of about 28 days. After the end of a menstrual period, the anterior pituitary releases follicle-stimulating hormone (FSH), which promotes the growth of a follicle in the ovary. The follicle nurtures the ovum (egg cell) and produces several types of estrogen, including estradiol. Toward the middle of the menstrual cycle, the follicle builds up more and more receptors to FSH, so even though the actual concentration of FSH in the blood is decreasing, its effects on the follicle increase.

As a result, the follicle produces increasing amounts of estradiol. The increased release of estradiol causes an increased release of FSH as well as a sudden surge in the release of luteinizing hormone (LH) from the anterior pituitary. FSH and LH combine to cause the follicle to release an ovum. The remnant of the follicle (now called the corpus luteum) releases the hormone progesterone, which prepares the uterus for the implantation of a fertilized ovum. Progesterone also inhibits the further release of LH. If the woman is pregnant, estradiol and progesterone levels continue to increase. If she is not pregnant, both hormones decline, the lining of the uterus is cast off (menstruation), and the cycle begins again.

For humans, the results concerning female sexual arousal are a bit more complex. When researchers compared young married women, they found that frequency of sexual intercourse correlated highly with the amount of testosterone that women produced at the periovulatory period, the days around the middle of the menstrual cycle, when fertility is highest. However, a study comparing women’s increases and decreases of sexual interest from day to day across one or two months found that sexual desire correlated strongly with changes in levels of estradiol, not testosterone. Many women report a drop in sexual desire after surgical removal of their ovaries, resulting in lower estradiol levels.

TOPICS: 10.1 Sex and Hormones 118. Give some examples of evolutionary interpretations of mating behavior.

ANSWER: More men than women seek opportunities for casual sexual relationships with many partners.

Why? From the evolutionary standpoint of spreading one’s genes, men can succeed by either of two strategies: Be loyal to one woman and devote your energies to helping her and her babies, or mate with many women and hope that some of them can raise your babies without your help. No one needs to be conscious of these strategies, of course. The idea is that men who acted these ways in the past propagated their genes, and today’s men might have inherited genes that promote these behaviors. In contrast, a woman can have no more than one pregnancy per 9 months, regardless of her number of sex partners. So evolution may have predisposed men, or at least some men, to be more interested in multiple mates than women are.

Almost all people prefer a romantic partner who is healthy, intelligent, honest, and physically attractive. Typically, women have some additional interests that are less common for men. In particular, women are more likely than men are to prefer a mate who is likely to be a good provider. According to evolutionary theorists, the reason is this: While a woman is pregnant or taking care of a small child, she needs help getting food and other requirements. Evolution would have favored any gene that caused women to seek good providers. Related to this tendency, most women tend to be cautious during courtship. Even if a man seems interested in her, a woman is generally cautious before concluding that he has a strong commitment to her. She would not want a man who acts interested and then leaves when she needs him.

Men tend to have a stronger preference for a young partner. An evolutionary explanation is that young women are likely to remain fertile longer than older women are, so a man can have more children by pairing with a young woman. Men remain fertile into old age, so a woman has less need to insist on youth. Women prefer young partners when possible, but in many societies, only older men have enough financial resources to get married.

Traditionally, in nearly all cultures, men have been more jealous of a wife’s possible infidelity than women have been of a husband’s infidelity. From an evolutionary standpoint,

why? If a man is to pass on his genes—the key point in evolution—he needs to be sure that the children he supports are his own. An unfaithful wife threatens that certainty. A woman knows that any children she bears are her own, so she does not have the same worry. (She might, however, worry that her husband might start supporting some other woman’s children, instead of her own children.) The degree of jealousy varies among cultures. Some cultures tolerate sexual infidelity by husbands, and some do not, and the intensity of prohibition against wives’ infidelity varies, but no known society considers infidelity more acceptable for women than for men.

Which would upset you more: if your partner had a brief sexual affair with someone else, or if he or she became emotionally close to someone else? According to several studies, men say they would be more upset by the sexual infidelity, whereas women would be more upset by the emotional infidelity. However, those studies dealt with hypothetical situations. Most men and women who have actually dealt with an unfaithful partner say they were more upset by their partner’s becoming emotionally close to someone else than by the sexual affair.

TOPICS: 10.2 Variations in Sexual Behavior 119. Describe some of the evidence that genetic factors may influence sexual orientation.

ANSWER: Studies of the genetics of sexual orientation have focused mainly on twins. Early studies of the genetics of human sexual orientation began by advertising in gay or lesbian publications for homosexual people with twins. Then they contacted the other twin to fill out a questionnaire. The questionnaire included diverse items to conceal the fact that the real interest was sexual orientation. The results showed a stronger concordance for monozygotic than dizygotic twins. That is, if one twin is homosexual, the probability for the other to be homosexual is fairly high for a monozygotic twin, and less high for a dizygotic twin.

However, the kind of person who answers an ad in a gay or lesbian magazine may not be representative of others. A later study examined the data from all the twins in Sweden between ages 20 and 47. The Swedish study differed not only in the breadth of the sample, but also in the behavioral criterion. Instead of asking about sexual orientation, the researchers asked whether someone had ever had a same-sex partner. The results do not indicate number of people with homosexual activity or orientation. Rather, they indicate concordance—the probability of homosexual activity or orientation in one twin, given that the other twin had already indicated such activity. Although both sets of results show a higher concordance for monozygotic than dizygotic twins, there is huge difference between the studies. Other studies of twins in several countries also found higher concordance for sexual orientation in monozygotic than dizygotic twins, but the magnitude of the effect has varied considerably.

Several studies have looked for a particular gene that might be linked to sexual orientation, but they failed to find anything with a significant effect. Two studies reported a higher incidence of homosexuality among the maternal than paternal relatives of homosexual men.

For example, uncles and cousins on the mother’s side were more likely to be homosexual than uncles and cousins on the father’s side. These results suggested a gene on the X chromosome, which a man necessarily receives from his mother. However, other studies have found no difference between relatives on the mother’s and father’s side and one study found more homosexual relatives on the father’s side. Consequently, it seems unlikely that any gene on the X chromosome plays a major role.

120. Describe some of the evidence that brain anatomy may differ as a function of sexual orientation.

ANSWER: Do brains also differ as a function of sexual orientation? The results are complex. On average, homosexual men are shifted partly in the female-typical direction for some brain structures but not others. Similarly, on average, homosexual women’s brains are slightly shifted in the male direction in some ways but not others. Several of the reported differences have no clear relationship to sexuality itself, although they may relate to other behavioral differences between heterosexual and homosexual people.

On average, the left and right hemispheres of the cerebral cortex are of nearly equal size in heterosexual females, whereas the right hemisphere is a few percent larger in heterosexual males. Homosexual males resemble heterosexual females in this regard, and homosexual females are intermediate between heterosexual females and males. Also, in heterosexual females, the left amygdala has more widespread connections than the right amygdala, whereas in heterosexual males, the right amygdala has more widespread connections. Again, homo- sexual males resemble heterosexual females in this regard, and homosexual females are intermediate. The anterior commissure is, on average, larger in heterosexual women than in heterosexual men. In homosexual men, it is at least as large as in women, perhaps even slightly larger. The suprachiasmatic nucleus (SCN) is also larger in homosexual men than in heterosexual. However, when interpreting these and other reported differences, we should remember two cautions: First, we don’t know whether these brain differences are causes or effects of sexual orientation. Brain differences can predispose to different behaviors, but it is also true that persistent behaviors can change brain anatomy. Second, it is relatively easy to publish results showing a difference between two groups, such as homosexual and heterosexual people, even if the difference was unpredicted, small, and hard to explain. It is less easy to publish results showing no difference. Thus it is possible, even likely, that the published papers overstate certain anatomical differences.

The most widely cited research concerns the third interstitial nucleus of the anterior hypothalamus (INAH-3), which is generally more than twice as large in heterosexual men as in women. This area has more cells with androgen receptors in men than in women, and probably plays a role in sexual behavior, although the exact role is uncertain and probably varies among animal species. Simon LeVay examined INAH-3 in 41 people who had died between the ages of 26 and 59. Of these, 16 were heterosexual men, 6 were heterosexual women, and 19 were homosexual men. All of the homosexual men, 6 of the 16 heterosexual men, and 1 of the 6 women had died of AIDS. LeVay found that the mean volume of INAH3 was larger in heterosexual men than in heterosexual women or homosexual men, who were about equal in this regard. The difference between heterosexual men and the other two groups is fairly large, on average, and that the cause of death (AIDS versus other) has no clear relationship to the results.

A later study partly replicated these trends. Researchers found that the INAH-3 nucleus was slightly larger in heterosexual than homosexual men, although in this study the homosexual men’s INAH-3 nucleus was larger than that of heterosexual women. Still another study found INAH-3 to be larger in heterosexual males than in male-to-female transsexuals—that is, people born as males who changed their identities to female.

The meaning of these results is not clear. Do differences in the hypothalamus influence sexual orientation, or does sexual activity influence the size of hypothalamic neurons? Some brain areas do grow or shrink in adults because of hormones or behavioral activities. About 8 percent of rams (male sheep) direct their sexual behavior toward other males. One area of the anterior hypothalamus is larger in female-oriented rams than in male-oriented rams and larger in male-oriented rams than in females. This area becomes larger in male than female sheep before birth as a result of prenatal testosterone levels. In sheep, at least, an anatomical

difference appears before any sexual behavior, and so it is more likely a cause than a result.

The same may or may not be true in humans.

TOPICS: 12.2 Attack and Escape Behaviors Essay 116. Briefly describe the James-Lange Theory of Emotion.

ANSWER: According to the James-Lange theory (James, 1884), the autonomic arousal and skeletal actions come first. What you experience as an emotion is the label you give to your responses: You feel afraid because you run away, and you feel angry because you attack. The James-Lange theory leads to two predictions: People with weak autonomic or skeletal responses should feel less emotion, and causing or increasing someone’s responses should enhance an emotion.

TOPICS: 11.1 What is Emotion?

117. Briefly describe the role of the left and right hemispheres contribution to emotions according to Jeffrey Gray.

Activity of the left hemisphere, especially its frontal and temporal lobes, relates to what is called the Behavioral Activation System (BAS), marked by low to moderate autonomic arousal, and a tendency to approach, which could characterize either happiness or anger.

Increased activity of the frontal and temporal lobes of the right hemisphere is associated with the Behavioral Inhibition System (BIS), which increases attention and arousal, inhibits action, and stimulates emotions such as fear and disgust.

ANSWER:

118. Briefly describe how benzodiazepines work in the brain.

ANSWER: Benzodiazepines bind to the GABAA receptor, which includes a site that binds GABA as well as sites that modify the sensitivity of the GABA site. When a benzodiazepine molecule attaches, it neither opens nor closes the chloride channel but twists the receptor so that the GABA binds more easily. Benzodiazepines thus facilitate the effects of GABA. Benzodiazepines exert their anti-anxiety effects in the amygdala, hypothalamus, midbrain, and several other areas DIFFICULTY: Bloom’s: Understand REFERENCES: Anxiety Disorders LEARNING OBJECTIVES: KALA.BIOP.16.11.06 - Comment on methods of relief from anxiety.

TOPICS: 11.2 Attack and Escape Behaviors 119. Briefly describe the role of the HPA axis and the autonomic nervous system (ANS) in the stress response.

ANSWER: The ANS reacts very quickly to prepare the body for "fight or flight" by increasing heart rate, blood pressure, decreasing stomach secretions, etc.

The HPA axis reacts more slowly, resulting in the release of cortisol from the adrenal gland.

Cortisol helps the body mobilize energy. However, prolonged HPA activation can lead to immune suppression and deterioration of the hippocampus, resulting in impaired memory.

TOPICS: 11.3 Stress and Health 120. Describe the role of heredity and environment of violent behavior.

ANSWER: As with almost anything else in psychology, individual differences depend on both heredity and environment. Many environmental factors are easy to identify. Certainly people who were abused in childhood, people who witnessed violent abuse between their parents, and people who live in a violent neighborhood are at greater risk of violence themselves. People who have found success in the past by fighting are more likely than others are to fight again.

Within any country, violence tends to increase as the weather grows hotter.

Another factor is exposure to lead, which is harmful to developing brains. Since the banning of lead-based paints and the rise of unleaded gasoline, the prevalence of violent crime has declined, possibly as a result of the decreased lead in the environment.

What about heredity? Monozygotic twins resemble each other more closely than dizygotic twins do with regard to violent and criminal behaviors, and adopted children resemble their biological parents more closely than their adoptive parents. Genes influence violent behavior in many ways, including autonomic arousal. People with lower than average autonomic arousal tend, on average, to be more aggressive, probably because they react less strongly to fear of the consequences. Researchers found that 1-year-old infants with low autonomic arousal were more likely than average to show aggressive, antisocial behaviors when they reached age 3. However, various kinds of aggressive behavior occur under different circumstances, and we cannot expect to find a single gene or set of genes that will account for all the variations in all populations. For example, researchers found one gene linked to aggressive behavior that is common only among people of Finnish ancestry.

After researchers repeatedly failed to find a strong link between aggressive behavior and any single gene, they explored the possibility of interactions between heredity and environment.

Particularly interesting is the gene controlling the enzyme monoamine oxidase A (MAOA).

After a neuron releases serotonin, dopamine, or norepinephrine, most of it returns to the

neuron via reuptake. At that point the enzyme MAOA breaks down some of it, preventing possible accumulation of an excessive amount. People vary in their genes for MAOA, as some people have a less-active form of the gene. Considering the previous discussion of how low serotonin increases the probability of aggression, we might predict that the more active form of MAOA would link to aggression, because it breaks down serotonin and leaves less available for release. Contrary to this prediction, the low-activity form shows more link to aggression. However, the effect of the gene depends on prior experience. A pioneering study reported that the low-activity form of the gene increased violent behavior only in people who had a seriously troubled childhood environment, such as being physically abused or watching parents fight. This result is fascinating because of its apparent demonstration of an interaction between genetics and environment.

Since then, although some studies failed to replicate this finding, most studies did. The lowactivity form of the gene is uncommon in most populations. Because it is an X-linked gene, far more men than women have just the low-activity form of the gene. It may, therefore, contribute to the greater prevalence of violent behavior in men than in women.

Overall, what can we say about the biological bases of aggressive behavior? At this point, not much is clear. Low serotonin activity is weakly associated with increased aggression, but the form of the MAOA gene that strongly breaks down serotonin links to less aggression, and only for people with a history of childhood maltreatment. In any case, the effects are small. If we want to control human violence, biological interventions are probably not the most promising route.

ANSWER: Explicit memory, or declarative memory, is deliberate recall of information that one recognizes as a memory. If you have an explicit or declarative memory of something, you can state it in words. Procedural memory, the development of motor skills and habits, is a special kind of implicit memory. As with other examples of implicit memory, you might not be able to describe a motor skill or habit in words, and you might not even recognize it as a memory.

TOPICS: 12.1 Learning, Memory, and Amnesia 117. What is the primary cause of Korsakoff’s syndrome and what is one of its most distinctive symptoms?

ANSWER: Korsakoff ’s syndrome, also known as Wernicke-Korsakoff syndrome, is brain damage caused by prolonged thiamine deficiency. Severe thiamine deficiency occurs mostly in chronic alcoholics who go for weeks at a time on a diet of nothing but alcoholic beverages, lacking in vitamins. The brain needs thiamine (vitamin B1) to metabolize glucose, its primary fuel. Prolonged thiamine deficiency leads to a loss or shrinkage of neurons throughout the brain.

A distinctive symptom of Korsakoff’s syndrome is confabulation, in which patients fill in memory gaps with guesses. (Some patients with other disorders also confabulate.) Most confabulated answers are more pleasant than the currently true answers (Fotopoulou, Solms, & Turnbull, 2004). That tendency may reflect the patient’s attempt to maintain pleasant emotions or merely the fact that the patient’s past life was, on the whole, more pleasant than the present.

TOPICS: 12.1 Learning, Memory, and Amnesia 118. Describe how habituation is demonstrated in memory research on invertebrates?

ANSWER: Habituation is a decrease in response to a stimulus that is presented repeatedly and accompanied by no change in other stimuli. For example, if your clock chimes every hour, you gradually respond less and less. If we repeatedly stimulate an Aplysia’s gills with a brief jet of seawater, it withdraws at first, but after many repetitions, it stops responding. The decline in response is not due to muscle fatigue because, even after habituation has occurred, direct stimulation of the motor neuron produces a full-size muscle contraction (Kupfermann, Castellucci, Pinsker, & Kandel, 1970). We can also rule out changes in the sensory neuron.

The sensory neuron still gives a full, normal response to stimulation; it merely fails to excite the motor neuron as much as before (Kupfermann et al., 1970). We are therefore left with the conclusion that habituation in Aplysia depends on a change in the synapse between the sensory neuron and the motor neuron.

TOPICS: 14.4 Social Neuroscience 116. Briefly discuss the concept of a language acquisition device and its genetic basis.

ANSWER: Noam Chomsky (1980) and Steven Pinker (1994) proposed that humans have a language acquisition device, a built-in mechanism for acquiring language. Most children develop language so quickly and easily that it seems they must have been biologically prepared for this learning. Also, deaf children quickly learn sign language, and if no one teaches them a sign language, they invent one and teach it to one another (Goldin-Meadow, McNeill, & Singleton, 1996; Goldin-Meadow & Mylander, 1998).

DIFFICULTY: REFERENCES:

Researchers have begun to explore the genetic basis of this preparation for language. A family whose members have trouble with pronunciation and basic grammar is one such case.

Their problem has been shown to stem from a mutation in a gene designated FOXP2, which regulates a protein that promotes synapse formation in the cerebral cortex (Lai et al., 2001; Sia, Clem, & Huganir, 2013). Although both humans and chimpanzees have that gene, it differs in two places, resulting in proteins with different amino acids at two sites. That gene produces not only a multitude of effects, partly on brain development, but also on structures of the jaw and throat that are important for speech (Konopka et al., 2009).

LEARNING OBJECTIVES: KALA.BIOP.16.13.04 - Discuss hypotheses of how human language evolved.

TOPICS: 13.2 Evolution and Physiology of Language 117. What is Broca’s apahsia and which areas of the brain does it affect?

ANSWER: When brain damage impairs language production, we call it Broca’s aphasia, or nonfluent aphasia, regardless of the exact location of damage. This discovery, the first demonstration of the function of a particular brain area, paved the way for modern neurology.Modern methods have confirmed that Broca’s area contributes to language production, and research has identified regions within Broca’s area that contribute to language in distinct ways (Poeppel, Emmorey, Hickok, & Pylkkänen, 2012; Sahin, Pinker, Cash, Schomer, & Halgren, 2009).

Nevertheless, damage limited to Broca’s area produces only minor or brief language impairment. Speaking activates much of the brain, mostly in the left hemisphere, and not just Broca’s area (Wallesch, Henriksen, Kornhuber, & Paulson, 1985). Every area that contributes to language contributes to other behaviors as well, and the role of each area can change over time, especially in response to damage of another area (Blumstein & Amso, 2013).

Subcortical areas are important, too. Substantial aphasia can result from damage to areas of the basal ganglia that lie interior to Broca’s area of the cortex (Damasio, Damasio, Rizzo, Varney, & Gersh, 1982; Fyndanis, 2012; Naeser et al., 1982). In fact, most cases of Broca’s aphasia related to combined damage to parts of the cortex, thalamus, and basal ganglia.

TOPICS: 13.2 Evolution and Physiology of Language 118. Describe some of the research on in-group bias with respect to empathy and altruism.

ANSWER: Moral and religious leaders teach us that we should extend kindness to everyone, but in fact, most people tend to be more generous toward those they see as similar to themselves. For example, if you watch someone who is feeling socially rejected by others, you will “feel the pain” and your brain will react accordingly, but you will react more strongly if the person feeling rejected is one of your relatives or close friends. From an evolutionary standpoint, it makes sense to be altruistic toward your relatives, and someone who seems similar is more likely to be related to you than someone very different. However, the strength of this ingroup bias varies among individuals. Most people show brain responses that differ in several ways between viewing faces of their own race versus faces of another race, but the difference is greater in people with a strong bias toward their own race.

TOPICS: 13.4 Social Neuroscience 119. Discuss the three forms of monism ANSWER: Materialism: the view that everything that exists is material, or physical. According to one version of this view, “eliminative materialism,” mental events don’t exist at all, and any folk psychology based on minds and mental activity is fundamentally mistaken. However, most of us find it difficult to believe that our minds are figments of our imagination! A more plausible version is that we will eventually find a way to explain all psychological experiences in purely physical terms.

Mentalism: the view that only minds really exist and that the physical world could not exist unless some mind were aware of it. The philosopher George Berkeley was the primary defender of this position. It is not easy to test this idea.

Identity position: the view that mental processes and certain kinds of brain processes are the same thing, described in different terms. By analogy, one could describe the Mona Lisa as an extraordinary painting, or one could list the exact color and brightness of each point on the painting. Although the two descriptions appear entirely different, they refer to the same object DIFFICULTY: Bloom’s: Analyze REFERENCES: The Mind–Brain Relationship LEARNING OBJECTIVES: KALA.BIOP.16.13.07 - Explain why nearly all neuroscientists and philosophers favor some version of monism with regard to the mind–brain relationship.

TOPICS: 13.3 Conscious and Unconscious Processes and Attention 120. Provide a detailed description of spatial neglect.

ANSWER: Brain damage can produce special types of attention problems. Many people with damage to the right hemisphere show spatial neglect—a tendency to ignore the left side of the body, the left side of objects, much of what they hear in the left ear, and much of what they feel in the left hand, especially in the presence of any competing sensation from the right side. Some people have been known to put clothes on only the right side of the body. These effects are most pronounced early after a stroke or other damage, and most people show at least partial recovery over the next 10 to 20 weeks. (Damage in the left hemisphere seldom produces significant neglect of the right side.) If asked to point straight ahead, most patients with neglect point to the right of center. If a patient with neglect is shown a long horizontal line and asked to divide it in half, generally he or she picks a spot well to the right of center, as if part of the left side wasn’t there DIFFICULTY: Bloom’s: Analyze REFERENCES: Attention LEARNING OBJECTIVES: KALA.BIOP.16.13.01 - Identify the primary functions of the left and right hemispheres.

TOPICS: 14.3 Schizophrenia Essay 117. Define major depression.

ANSWER: Everyone has times of feeling discouraged. Major depression is much more intense and prolonged. People with a major depression feel sad and helpless most of the day every day for weeks at a time. They don’t enjoy anything and can hardly even imagine enjoying anything. They lack energy, feel worthless, contemplate suicide, have trouble sleeping, and cannot concentrate. When they have unpleasant thoughts, they have trouble getting rid of them (Foland-Ross et al., 2013). Changes in the synapses to the nucleus accumbens make it less responsive to reward (Russo & Nestler, 2013).

TOPICS: 14.2 Mood Disorders 118. Briefly describe the four major categories of antidepressant drugs ANSWER: Antidepressant drugs fall into several categories, including tricyclics, selective serotonin reuptake inhibitors, monoamine oxidase inhibitors, and atypical antidepressants. The tricyclics (e.g., imipramine, trade name Tofranil) operate by blocking the transporter proteins that reabsorb serotonin, dopamine, and norepinephrine into the presynaptic neuron after their release. The selective serotonin reuptake inhibitors (SSRIs) are similar to tricyclics but specific to the neurotransmitter serotonin. The monoamine oxidase inhibitors (MAOIs) (e.g., phenelzine, trade name Nardil) block the enzyme monoamine oxidase (MAO), a presynaptic enzyme that metabolizes catecholamines and serotonin into inactive forms. The atypical antidepressants include everything other than the types just discussed (Horst & Preskorn,

1998). One example is bupropion (Wellbutrin), which inhibits reuptake of dopamine and to some extent norepinephrine but not serotonin. Although antidepressants vary in which neurotransmitter(s) they target—serotonin, dopamine, norepinephrine, or some combination—all appear to be nearly equal in their effectiveness (Montgomery et al., 2007).

TOPICS: 14.4 Autism Spectrum Disorders 120. Describe the difference between positive and negative symptoms of schizophrenia and give some examples of each.

ANSWER: Positive symptoms include manifest behaviors that should be absent, such as delusions (unfounded beliefs), hallucinations (abnormal sensory experiences), disorganized speech, and grossly disorganized behavior. Each of these is a judgment call. Sometimes a statement that appears to be a delusion (“People are persecuting me”) is actually true, or at least defensible.

Many healthy people have heard a voice when they knew they were alone, most often when they were just waking up.

Negative symptoms include absent behaviors that should be present, such as weak social interactions, emotional expression, speech, and working memory. Negative symptoms are usually stable over time and difficult to treat.

TOPICS: 14.3 Schizophrenia 121. Describe the differences between antagonists and agonists.

ANSWER: Drugs either facilitate or inhibit transmission at synapses. A drug that blocks a neurotransmitter is an antagonist, whereas a drug that mimics or increases the effects is an agonist. (The term agonist is derived from a Greek word meaning “contestant.” The term agony derives from the same root. An antagonist is an “anti-agonist,” or member of the opposing team.) A mixed agonist–antagonist is an agonist for some effects of the neurotransmitter and an antagonist for others or an agonist at some doses and an antagonist at others.

ANSWER: The legal standard emphasizes “the three Rs”: reduction of animal numbers (using fewer animals), replacement (using computer models or other substitutes for animals, when possible), and refinement (modifying the procedures to reduce pain and discomfort).

TOPICS: INT.1 Overview and Major Issues KEYWORDS: New 108. Discuss the four biological explanations of behavior.

ANSWER: A physiological explanation relates a behavior to the activity of the brain and other organs. It deals with the machinery of the body—for example, the chemical reactions that enable hormones to influence brain activity and the routes by which brain activity controls muscle contractions.

An ontogenetic explanation describes how a structure or behavior develops, including the influences of genes, nutrition, experiences, and their interactions. For example, the ability to inhibit impulses develops gradually from infancy through the teenage years, reflecting gradual maturation of the frontal parts of the brain.

An evolutionary explanation reconstructs the evolutionary history of a structure or behavior.

The characteristic features of an animal are almost always modifications of something found in ancestral species. For example, bat wings are modified arms, and porcupine quills are modified hairs. In behavior, monkeys use tools occasionally, and humans evolved elaborations on those abilities that enable us to use tools even better. Evolutionary explanations call attention to behavioral similarities among related species.

A functional explanation describes why a structure or behavior evolved as it did. Within a small, isolated population, a gene can spread by accident through a process called genetic drift. For example, a dominant male with many offspring spreads all his genes, including some that helped him become dominant and other genes that were irrelevant or even disadvantageous. However, a gene that is prevalent in a large population probably provided some advantage—at least in the past, though not necessarily today. A functional explanation identifies that advantage.

TOPICS: INT.1 Overview and Major Issues 109. Discuss David Chalmers’s approach to consciousness and identify the problems associated with it.

ANSWER: Chalmers (2007) proposed that we regard consciousness as a fundamental property of matter.

A fundamental property is one that cannot be reduced to something else. For example, mass

and electrical charge are fundamental properties. Maybe consciousness is like that.

But it’s an unsatisfying answer. First, consciousness isn’t like other fundamental properties.

Matter has mass all the time, and protons and electrons have charge all the time. So far as we can tell, consciousness occurs only in certain parts of certain kinds of nervous systems, just some of the time— not when you are in a dreamless sleep, and not when you are in a coma.

Besides, it’s unsatisfying to call anything a fundamental property, even mass or charge. To say that mass is a fundamental property doesn’t mean that there is no reason. It means that we have given up on finding a reason. And, in fact, contemporary physicists have not given up.

They are trying to explain mass and charge in terms of the Higgs boson and other elements of the universe. To say that consciousness is a fundamental property would mean that we have given up on explaining it.

TOPICS: INT.1 Overview and Major Issues KEYWORDS: New 110. Describe the minimalist position on animal research.

ANSWER: “Minimalists” tolerate certain types of animal research but wish to prohibit others depending on the probable value of the research, the amount of distress to the animal, and the type of animal. (Few people have serious qualms about hurting an insect, for example.) They favor firm regulations on research. Researchers agree in principle, although they might differ in where they draw the line between acceptable and unacceptable research.
