Abstract

Neuromotor prosthetics: recruiting novel neurons Brain–machine interfaces are a promising approach for treating paralysis due to spinal cord injury, by rerouting control signals from the brain to the muscles. Previous work showed that monkeys can be trained to move robotic arms using signals from electrodes implanted in the brain. Now it is reported that monkeys can learn to move a temporarily paralysed wrist using signals artificially routed from single neurons in the brain that had not previously been associated with that movement. This may have significant implications for future design of brain–machine interfaces, which have traditionally relied on the activity of dedicated populations of neurons.
