An End to Paralysis with Artificial Brain-to-Muscle Connectors

Using a computerized connector between the brain and muscles in the body, scientists have been able to restore movement to paralyzed limbs. A group of neuroscientists report in Nature today that they used a brain-computer interface to join the motor cortex of an ape to the muscles in its wrist. After scientists paralyzed the ape’s arm temporarily, it was still able to make its wrist move my sending electrical impulses directly from its brain to the muscles, bypassing the damaged nerves in between. The study has profound implications for people whose nerves have been severed or damaged, leaving them paralyzed.
