In a major breakthrough, scientists at UC San Francisco developed technology to decode words from the brain activity of a paralyzed man who is unable to speak and translate them to text that appears on a screen. The technology, known as a “speech neuroprosthesis,” may hold promise for the thousands of people each year who lose speech owing to a stroke, accident or disease. We’ll talk to the researchers about their achievement.
