In a clinical trial, a paralysed man used the BCI to write text on a computer screen just by thinking about the movements involved in handwriting. It consists of a sensor that is implanted on the motor cortex of the brain and a device that analyses brain signals. The principle behind the BrainGate system is that with intact brain functionality, brain signals are generated even though they are not sent to the arms, hands, and legs. Researchers can therefore tap into the brain activity of people with paralysis or amputations to regain some of their lost abilities.
