After a paralyzing accident, one man thought he may never be able to talk again. However, an experimental device called BrainGate2 has given him his “voice” back. The man is able to type on a computer screen by imagining the letters on a sheet of paper. The device is 95 percent accurate and the man can think about 90 character per minute, which is faster than researchers thought. BrainGate2 helps people who are paralyzed use a computer by thinking the commands. The system uses electrodes that are inserted into the part of the brain that controls movement.
