Brain-computer interface enables independent, accurate communication for man living with ALS

“Casey can use the system to communicate his own thoughts, not only while we're there in a controlled environment, but whenever he wants. Sometimes, he would do that over 12 straight hours,” said the study’s lead author, Nicholas Card. Card is a postdoctoral scholar in the UC Davis Department of Neurological Surgery. “The system worked well, was reliable and stable, and delivered consistent results. This is one of the strongest demonstrations that BCIs can be practical and useful.”
