An AI-powered brain implant helps a quadriplegia patient regain sensations and movement for the first time after a diving accident in 2020. Can this implant work for other paralysis patients?
in the US alone. There are hardly any treatment options available that can significantly improve the condition of such patients.
However, the new implant raises hope as it shows a promising way to reconstruct lost neural pathways andThe diving accident damaged Keith’s C4 and C5 vertebrae , leaving him completely paralyzed below the chest region. While Keith was admitted to the hospital, he learned about the implant trial at Feinstein and became a participant.
The researchers needed to perform complex brain surgery to install the implant, but before that, they wanted to know which areas of Keith’s brain were affected. So they first conductedNext, they performed a 15-hour surgery on March 9, 2023, at North Shore University Hospital, during which they were trying to identify the right spot for the implant to work.
Dr. Ashest Mehta, one of the surgeons who performed the surgery, said, “Because we had Keith’s images and he was talking to us during parts of his surgery, we knew exactly where to place the brain implants. We inserted two chips in the area responsible for movement and three more in the part of the brain responsible for touch and feeling in the fingers.”
Keith’s condition has drastically improved since the surgery. For the first time in the last three years, he can feel the sensation when someone touches or holds his hand, and heThe researchers connected Keith’s head implants to computers in their lab so that the AI could convert his thoughts into actions. Once the commands are clear, the
