Brain control-Monkey

In a ground-breaking 5 year experiment, scientists hook up a robotic arm controlled by a computer game to a monkey's brain. In training the monkey to move the arm by 'playing' the game with a joystick. Researchers wanted to learn more about the output of the brain and the individual brain-cell signals. However the monkey was about to do something that would make history and change the lives of those involved. The clip is taken from a fascinating BBC Horizon show called Human2.0.
