People who break their backs or suffer a spinal trauma are unable to stand or move even though their legs still work, because the signal which connects their brain to their muscles is disconnected. An international team of scientists may have found a way to bypass the injury and reconnect the brain signals to electrodes at an undamaged part of the spine. The scientists created a device which mimics the natural communication of the brain and muscles, stimulating the nerves in the spine. The device has already worked in the brains of primates, and the team of scientists are hopeful it will work for humans as well.
