Revolutionary Implant Device Enables Paralyzed Man to Walk Again.

A paralysed man has regained the ability to walk smoothly using only his thoughts, thanks to a new device that connects his brain and his spinal cord, bypassing an injury he suffered 12 years ago. When he thinks about walking, electrodes on his brain relay the message to electrodes on his spinal cord, stimulating the spine. After about 40 rehabilitation sessions using the brain-spine interface, the man regained the ability to voluntarily move his legs and feet, and even walk short distances without the device if he uses crutches.
