Neurotransmitter: A neurochemical that transmits nerve impulses across a synapse and are found at axon endings of motor neurons and they stimulate muscle fibers.

GABA and GlycineInhibitory Neurotransmitters

GABA AND GLYCINE GABA and Glycine work together as Inhibitory neurotransmitters. Glycine is the amino acid which helps slow down processes and is located in the PNS. GABA also slows processes down in brain and works as the chief inhibitory neurotransmitter located in the mammalian CNS. As an Inhibitory neurotransmitter,

Medications for seizures, impulse control problems, and Bipolar Disorder all work by increasing the GABA levels within the brain. Anti-seizure medications increase GABA to the normal range, lowering the possibility of seizures and produce brain chemical stability.
