UC Davis BCI returns chat and work to Casey Harrell
A 47-year-old man with ALS, Casey Harrell, is back to chatting and working full time thanks to a brain-computer interface (BCI) created by UC Davis researchers.
The device translates neural signals into text so he can use a computer on his own (pretty amazing for someone with severe paralysis and speech impairment).
This breakthrough was just published in Nature Medicine.
Largest single-neuron dataset from Casey Harrell
Over two years, Casey has typed out almost two million words and more than 183,000 sentences at a speedy 56 words per minute with 92% accuracy.
The BCI lets him share memories with loved ones and keep up at work despite his paralysis.
Researchers also gathered 3,800 hours of his brain data, the biggest single-neuron dataset ever, which could help make even better technology for people with severe disabilities in the future.
