Brain implant allows paralyzed monkey to walk

Researchers at the Swiss Federal Institute of Technology in Lausanne have developed a neuroprosthetic interface that creates a wireless link between the brain and the spine. In a recent experiment, they used it to enable a paralyzed monkey to walk.

Via Healthglu:

The brain-spine interface overcomes a damaged connection by bridging the spinal cord injury — and it does so in real-time and via wireless technology. The neuroprosthetic device implanted in the monkey’s brain correctly interprets activity generated by the motor cortex, and relays this information to a system of electrodes placed over the surface of the spinal cord, just below the injury. A burst of just a few volts, delivered at the right location, triggers specific muscles in the legs. Monkeys implanted with the device were able to walk within six days of the spinal cord injury.
