Researchers have described how an electrode array on top of the brain enabled a 30-year-old man to control the movement of a character on a computer screen in three dimensions with just his thoughts. It also enabled him to reach out with a robot arm to touch a friend's hand for the first time in the seven years since he was paralyzed.
