Summary
A brain-computer interface (BCI) from the BrainGate clinical trial has, for the first time, restored fluent everyday speech to Casey Harrell, a man with ALS who had lost the ability to speak. The small implant translates his neural commands for speech directly into computer-synthesized words, allowing him to communicate for up to twelve hours at a stretch. This breakthrough represents a significant milestone in BCI technology for restoring natural communication to people with paralysis or speech loss.

· 3 pulledCasey Harrell can now talk for twelve hours at a stretch. Two years ago, he could not talk at all.
The ALS he was diagnosed with several years earlier had progressively destroyed the motor neurons controlling the muscles of his face and throat, leaving him with the symptoms doctors call dysarthria and, eventually, anarthria — the inability to speak intelligibly even with substantial effort.
The neural commands his brain was sending toward the muscles of his lips, tongue, jaw, and larynx were intact.
