This is amazing.
For the first time, a collaboration of scientists between the University of Pittsburgh and the University of Pittsburgh Medical Center have helped a paralyzed man, 30-year-old Nathan Copeland, experience the sense of touch from his mind-controlled robotic arm.
To achieve this breakthrough, the scientists implanted electrodes, smaller than a grain of sand, in the sensory cortex of Copeland’s brain. The electrodes received signals from a robot arm. When a researcher pressed the fingers of the prosthesis, Copeland felt the pressure in the fingers of his own paralyzed right hand, effectively bypassing his damaged spinal cord Washington Post Article.
Says Nathan of the sensation:
“I can feel just about every finger,” Copeland said Wednesday. “Sometimes it feels electrical, and sometimes it’s pressure, but for the most part, I can tell most of the fingers with definite precision. It feels like my fingers are getting touched or pushed.”
And this is in fingers that have felt nothing for some 10 years.
