A man who is unable to move or speak can now generate words and sentences on a computer using only his thoughts.
The ability comes from an experimental implanted device that decodes signals in the man's brain that once controlled his vocal tract, as researchers reported Wednesday in The New England Journal of Medicine.
The man is currently limited to a vocabulary of just 50 words and communicates at a rate of about 15 words per minute, which is much slower than natural speech.
"This tells us that it's possible," says Edward Chang, a neurosurgeon at the University of California, San Francisco. "I think there's a huge runway to make this better over time."
