Q. WHAT EXACTLY IS BRAINGATE?
A. It's a way for people who've been paralyzed by strokes, spinal cord injuries or A.L.S. to connect their brains to the outside world. The system uses a tiny sensor that's been implanted into the part of a person's brain that generates movement commands. This sensor picks up brain signals, transmits them to a plug attached to the person's scalp. The signals then go to a computer which is programmed to translate them into simple actions.
