Monkey's brain controls robot arm

Monkeys have been able to control robotic limbs using only their thoughts, scientists report. The animals were able to feed themselves using prosthetic arms, which were controlled by brain activity. Small probes, the width of a human hair, were inserted into the monkeys' primary motor cortex - the region of the brain that controls movement. Writing in the journal "Nature," the authors said their work could eventually help amputees and people who are paralyzed.
