Monkey Brains, Robot Arms May Aid Paralyzed People After Study

Scientists seeking to help paralyzed people use computers may have found a better way for them to steer a cursor, a study in rhesus monkeys suggests.
In some cases, paralyzed people have had electrodes implanted in their brains so they can interact with computers using electrical impulses triggered by their thoughts. The problem is they don’t get enough sensory feedback to precisely control cursor movement, said Nicholas Hatsopoulos, chairman of computational neuroscience at the University of Chicago.
