"The experiments The experiments involved monkeys that were trained to reach for either of two targets on a computer screen.
while two jittering targets were positioned on either side of a computer screen. Colored barriers on the screen created a simple maze.
When the targets stopped jittering the monkeys were trained to move to one or the other target by sweeping his fingertip through the maze until he touched one of the targets.
During the experiments, 192 electrodes in each monkey's motor and premotor cortex began measuring brain activity the moment that the targets appeared on screen.
