Beaten and left to die, his right brain smashed, one half of the brain severely damaged, the doctors said that if the man survived, he would be nothing more than a vegetable. For six years, he couldn't eat or speak, and only occasionally showed signs of conciousness, and tried to communicate by moving his eyes or a thumb. Doctors called his state "minimally conciousness".
Now he can eat, swallow and speak, thanks to electrodes planted in his brain.
