Brain implant helps man
"speak" through a computer |
|
A brain implant
has helped restore a type of speech to a man more than 15 years after a
stroke robbed him of the ability to speak, researchers reported
last week. They're
calling it a neuroprosthesis, and while it's only one patient for now, the
team at the University of California, San Francisco (UCSF) hopes their device
may help other paralyzed people communicate. "To
our knowledge, this is the first successful demonstration of direct decoding
of full words from the brain activity of someone who is paralyzed and cannot
speak," said Dr. Edward Chang, a neurosurgeon at UCSF who led the
research team. "It
shows strong promise to restore communication by tapping into the brain's
natural speech machinery," Chang said in a statement. ➕ Watch UCSF video: “Neuroprosthesis”
