In a medical first, brain implant allows paralyzed man to feel again
For the first time, scientists have helped a paralyzed man experience the sense of touch in his mind-controlled robotic arm.
For the cutting-edge experiment, a collaboration between the University of Pittsburgh and the University of Pittsburgh Medical Center, electrodes smaller than a grain of sand were implanted in the sensory cortex of the man’s brain. The electrodes received signals from a robot arm. When a researcher pressed the fingers of the prosthesis, the man felt the pressure in the fingers of his paralyzed right hand, effectively bypassing his damaged spinal cord
