Paralyzed Ohio man, 24, regains partial use of hand via brain chip implant

NEW YORK – A paralyzed 24-year-old man has regained some use of his right hand, controlling it with signals relayed from electronic sensors in his brain. Ian Burkhart of Dublin, Ohio, can grasp a bottle, pour its contents into a jar, pick up a stick and stir the liquid. He can grab a credit card and swipe it through a reader. He can move individual fingers and hold a toothbrush. But he can do these things only for a few hours a week, in a laboratory where he is hooked up to an experimental device that interprets his brain signals and stimulates his muscles with electrodes on his forearm.
