Such devices tap into the relevant regions of the brain, bypass damaged connections and deliver thought commands to devices such as virtual keypads.īut brains are complex. In recent years researchers have sought to give people suffering from injury or disease some restored motor function by developing thought-controlled prostheses. When we type or perform other precise tasks, our brains and muscles usually work together effortlessly.īut when a neurological disease or spinal cord injury severs the connection between the brain and limbs, once-easy motions become difficult or impossible. It takes 11.4 seconds to hit 10 targets using the thought-control device. In the first clip the monkeys hit 10 targets in 9.9 second with their hands. This device discerns their intention to hit the target and translates this thought into an electronic command that controls a virtual cursor.
But this time, the motion is directed by an experimental device that taps into the monkey’s brain. The second clip also shows targets being hit. In the first, flashing targets on a virtual keypad are hit by monkeys (not shown) using their hands.
