Medical First - brain waves of a paralyzed man print his words on computer screen

AP - https://apnews.com/article/technology-science-health-2034d0fff5e63a83b7add3e991df79b1">In a medical first, researchers harnessed the brain waves of a paralyzed man unable to speak — and turned what he intended to say into sentences on a computer screen.



It will take years of additional research but the study, reported Wednesday, marks an important step toward one day restoring more natural communication for people who can't talk because of injury or illness.



"Most of us take for granted how easily we communicate through speech," said Dr. Edward Chang, a neurosurgeon at the University of California, San Francisco, who led the work. "It's exciting to think we're at the very beginning of a new chapter, a new field" to ease the devastation of patients who lost that ability.

"It's exciting to think we're at the very beginning of a new chapter, a new field" to ease the devastation of patients who lost that ability.



Today, people who can't speak or write because of paralysis have very limited ways of communicating. For example, the man in the experiment, who was not identified to protect his privacy, uses a pointer attached to a baseball cap that lets him move his head to touch words or letters on a screen. Other devices can pick up patients' eye movements. But it's a frustratingly slow and limited substitution for speech.



Volunteering to test the device was a man in his late 30s who 15 years ago suffered a brain-stem stroke that caused widespread paralysis and robbed him of speech. The researchers implanted electrodes on the surface of the man's brain, over the area that controls speech.



A computer analyzed the patterns when he attempted to say common words such as "water" or "good," eventually becoming able to differentiate between 50 words that could generate more than 1,000 sentences.



--------- How did they know the device interpreted his words correctly? They started by having him try to say specific sentences such as, "Please bring my glasses," rather than answering open-ended questions until the machine translated accurately most of the time.

Right on. Good start.

I know a retired railroader that hasn't spoke since 2015 due to a major stroke. This is great news.

This is a terrific technological advancement cc.

I hope he doesn't get in trouble when the machine prints out "Wow that nurse has a nice ass".

It's good thing for patients Shen Li isn't allowed to hold needles or scalpels.
