- “A medical first” (Associated Press).
- Chang, University of California, San Francisco, and his team worked on “decoding brain waves” - think of it like reading someone’s mind.
- Electrodes placed on the brain’s speech center pick up on the brain waves that connect to language production. As the person thinks of a word, their brain fires off instructions for certain muscles to move. Chang’s computer translates these tiny signals into words.
- The first participant: a man in his 30s who suffers from paralysis after a brain-stem stroke.
- How it worked: Words appeared as text on a computer screen a few seconds after the man thought them.
- Why This Matters: This cutting-edge technology is called “speech neuroprosthetic” - a new scientific field of work carrying great potential for people whose physical speech is inhibited.
