AI and a brain implant restored a paralysed man's movement and touch

TLDR · 2 hours ago

Researchers restored hand movement and touch sensation to a paralyzed man using a system combining brain implants, AI decoding, and spinal cord stimulation. After 35 weeks of training, the participant's right arm strength increased 86% and he regained feeling in his wrist; these gains persisted over two years after stimulation stopped. The technology appears to rewire the nervous system rather than temporarily bypass the injury, with the AI decoder maintaining 84.6% accuracy over five months without retraining.
