Researchers have developed an electrical device that has helped a quadriplegic man to move his hand, wrist and several fingers, enabling him to carry out basic movements such as picking up a bottle and pouring a glass of water.
The device is a brain implant that works by picking up the man’s thoughts and transmitting them to a computer, which then decodes the thoughts and sends electrical signals to a sleeve of electrodes worn on his forearm. The sleeve then stimulates his muscles and enables him to carry out movements.
