"Brain-spine implants enable paralyzed man to walk again"

A brain-spine interface device has enabled a man with a spinal cord injury to walk again. The device creates a "digital bridge" between the brain and nerves below the injury, allowing the patient to control the stimulation of the lower spine with electrical pulses. The system makes use of a spinal implant and two disc-shaped implants inserted into the skull. The skull implants detect electrical activity in the cortex, which is wirelessly transmitted and decoded by a computer that the patient wears in a backpack. After around 40 rehabilitation sessions, the patient regained the ability to voluntarily move his legs and feet.
