Researchers at Northwestern University have developed a neuroprosthesis that restores complex movement in the paralyzed hands of monkeys. By implanting a multi-electrode array directly into the brain of the monkeys, they were able to detect the signals that generate arm and hand movements. These signals were deciphered by a computer and relayed to a functional electrical stimulation (FES) device, bypassing the spinal cord to deliver an electrical current to the paralyzed muscles. With a lag time of just 40 milliseconds, the system enabled voluntary and complex movement of a paralyzed hand. .. Continue Reading Neuroprosthesis restores hand movement in paralyzed monkeys
