Elon Musk’s Neuralink is coming soon, but researchers at Feinstein Institutes have already helped a paralyzed man feel again using brain implants and AI technology. Put simply, the team implanted microchips into the brain of a man living with paralysis and then developed artificial intelligence algorithms to reconnect his brain to his body and spinal cord.
This 15-hour, open-brain procedure, called double neural bypass, essentially forms an electronic bridge that re-links Keith Thomas’ paralyzed body and brain to restore movement as well as sensations in his hand. The bypass process begins with Mr. Thomas’ intentions, such as thinking about squeezing his hand, which triggers electrical signals from his brain implant to a computer. The computer then transmits these signals to highly-flexible, non-invasive electrode patches that are placed over his spine and hand muscles located in his forearm to stimulate function and recovery.

When the study participant thinks about moving his arm or hand, we ‘supercharge’ his spinal cord and stimulate his brain and muscles to help rebuild connections, provide sensory feedback, and promote recovery. This type of thought-driven therapy is a game-changer. Our goal is to use this technology one day to give people living with paralysis the ability to live fuller, more independent lives,” said Chad Bouton, professor in the Institute of Bioelectronic Medicine at the Feinstein Institutes.
