Monkeys control robots with their minds

Scientists at the University of Pittsburgh have trained a group of monkeys to feed themselves marshmallows using a robot arm controlled by sensors implanted in their brains. The feat could one day help paralyzed people operate prosthetic limbs on their own, researchers said. Researchers added that they believe it won’t be long before the technology is tested in humans, but they predict it will be longer before the devices are used in actual patients with disabilities.
