“Scientists in North Carolina have built a brain implant that lets monkeys control a robotic arm with their thoughts, marking the first time that mental intentions have been harnessed to move a mechanical object.

The technology could someday allow people with paralyzing spinal cord injuries to operate machines or tools with their thoughts as naturally as others today do with their hands. It might even allow some paralyzed people to move their own arms or legs again, by transmitting the brain’s directions not to a machine but directly to the muscles in those latent limbs.”
