Paralyzed man walks again with brain-spine interface made of electrodes on his brain and spinal cord

Researchers developed electrical implants, known as a brain-spine interface, that connect a patient's brain and spinal cord, allowing him to walk, climb stairs and overcome uneven terrain.
The interface transmits signals from the brain to the spinal cord, stimulating leg muscles and restoring communication between the two regions of the central nervous system interrupted by a spinal cord injury.
A 40-year-old paralyzed man who received the implants, known as Gert-Jan Oskam, was able to stand, walk and climb stairs after years of physical therapy and training with the device.
Oskam's quality of life has significantly improved thanks to the implants, though researchers hope to miniaturize the technology to increase portability and accessibility.
The success of the implants in restoring Oskam's mobility suggests the technology could help patients with other neurological disorders like stroke as well as arm and hand paralysis.
