AI-enabled brain implant helps patient regain feeling and movement
Keith Thomas from New York was involved in a driving accident back in 2020 that injured hisC4 and C5 vertebrae, leading to a total loss in feeling and movement from the chest down. Recently, though, Thomas had been able to move his arm at will and feel his sister hold his hand, thanks to the AI brain implant technologyspent months
mapping his brain with MRIs to pinpoint the exact parts of his brain responsible for arm movements and the sense of touch in his hands. Then, four months ago, surgeons performed a 15-hour procedure to implant microchips into his brain — Thomas was even awake for some parts so he could tell them what sensations he was feeling in his hand as they probed parts of the organ.
While the microchips are inside his body, the team also installed external ports on top of his head. Those ports connect to a computer with the artificial intelligence algorithms that the team developed to interpret his thoughts and turn them into action. The researchers call this approach"thought-driven therapy," because it all starts with the patient's intentions.
Thanks to this system, he was able to move his arm at will and feel his sister holding his hand in the lab. While he needed to be attached to the computer for those milestones, the researchers say Thomas has shown signs of recovery even when the system is off. His arm strength has apparently"more than doubled" since the study began, and his forearm and wrist could now feel some new sensations.
