BrainGate
Last May, news broke that the world was speeding into the realm of science fiction. Cathy Hutchinson, a woman left paralyzed in all four limbs due to a stroke, was able to drink a bottle of coffee using a robotic arm simply by imagining the action. Directed solely by

Hutchinson’s thoughts, the robot gave Hutchinson the ability to control her environment without a caretaker’s assistance for the first time in 15 years. Taking that independent sip, the then 58-year-old cracked a smile. This was the work of BrainGate2 Neural Interface System scientists, whose research aims to develop technology to restore com-
munication ability, mobility, and independence to people suffering from neurological disease, injury, or limb loss. Seven years ago, Case Western Reserve University’s own Robert Kirsch began working with the BrainGate2 team, comprised of scientists from Brown University and Massachusetts General Hospital. Now, Kirsch is bringing a trial

eline study home to Cleveland. While the BrainGate2 study as a whole revolves around general body-brain interface, the Cleveland trials specifically aim to recreate results more like Hutchinson’s. Kirsch, chair of the biomedical engineering department at CWRU, explained his team’s research goals. “Our specific twist on this is that we’re primarily focused on restoring arm and hand functions to people,” he said. “We’re really interested in helping restore movement.” As such, Kirsch’s team is working mainly with people suffering from spinal cord injuries. CWRU was an obvious place for BrainGate2 scientists to put a new clinical trial site focusing on movement restoration. It was in Cleveland, after all, that Hunter Peckham initially pioneered functional electrical stimulation (FES), technology that has since allowed researchers like Kirsch to make paralyzed limbs move again with electrical impulses. Kirsch wanted to take all that he had accomplished with FES to new heights, and BrainGate2 technol-

Campus experts debate gun control, concealed carry >>mikeMCKENNA asst.newsEDITOR<< >>suneilKAMATH
civic.engagement REPORTER<< In the wake of the tragedy at Sandy Hook Elementary, gun control has been of utmost debate in the country. Proponents of additional control say that further regulation would help curb gun violence while critics argue that taking away an individual’s ability to protect themselves would in fact make society more dangerous. This Wednesday, the discussion took a personal turn with Share the Vision and The Observer hosting a debate on the subject called “Guns, Our Community and Safety”. Dr. Mark Singer, co-director for the Center of Substance Abuse and Mental Illness, Arthur Hardee, Chief of CWRU Police and director of Security for CWRU, and Rylan Pyciak, President of
Spartans for Concealed Carry, presented their opinions on gun regulation and concealed carry on college campuses to a crowd of students in the 1914 lounge of Thwing. Singer and Hardee primarily were against concealed carry and were for tighter gun regulation, drawing from their work in their respective backgrounds, with Pyciak, who was raised in small town in Ohio and says he received his first gun at three years old, taking the opposition. In his opening statements, Singer emphasized carrying a gun responsibly requires more training than current conceal and carried regulations, and that having a gun in one’s home increases a person’s chance of being a victim of gun violence. Hardee agreed with Singer’s sentiment. “I don’t believe in guns on campus because it would send a very bad message to the community,” Hardee said. “The community and CWRU should collabo-

The panelists then touched on a variety of related issues, including how much defense a gun actually provides, the potential divide between gun carrying and noncarrying students, and how binge drinking or other reckless behavior could impact gun safety. A majority of audience questions seemed to take Pyciak’s
view, addressing Singer’s and Hardee’s stance that guns do more harm than the safety they provide. Kurtis Jensen, a Class of 2012 alum who works at University Hospitals, was one of the audience members who agreed with Pyciak. “It would be a good thing for a small percentage of people to hold guns on campus,” said Jensen. “It would serve as a deterrent for people wanting to commit crimes on campus. If they couldn’t tell who did or did not have a gun, they wouldn’t want to risk it.”
