Brain Implant Restores Speech To ALS Patient

A brain-computer interface developed by researchers at the University of California, Davis, has enabled a man with advanced ALS to communicate with remarkable accuracy, return to full-time employment, and use a computer independently for nearly two years, marking one of the most significant real-world demonstrations of the technology to date.

How The System Works

The breakthrough centres on Casey Harrell, a man living with amyotrophic lateral sclerosis (ALS), a progressive neurological condition that destroys motor neurons and can eventually leave people unable to speak or move.
