A New Brain Implant Lets Paralyzed Primates Walk Again
One research team created a wireless brain implant to successfully let two paralysed rhesus macaques walk again.
The wireless system works by bypassing spinal cord injuries and sends signal directly to the lumbar region rather than all the way down the spinal cord.
This is the first time a neural prosthetic restored movement in a primate.
Researchers included collaborators from Switzerland and Germany and added to a sensor technology called BrainGate. The small electrode gets implanted into the brain and gathers movement signals by the brain’s motor cortex.

The implants were tested on two primates that had paralysis from spinal cord lesions in their upper and middle back.
