Implant Restores Function in Barely Conscious Man

Stimulating electrodes in the brain of a minimally conscious person made him more able to talk, chew, swallow, and move his limbs.

Doctors tried the experimental treatment on a man left severely brain damaged after an assault more than six years ago. For years, the man barely interacted with people, only sometimes nodding yes or shaking his head no. Sometimes he would mouth a single word. Now, he can speak in phrases and even recited part of the Pledge of Allegiance.
