By looking only at maps of electrical activity in the human brain, scientists were able to tell which words a person was listening to. The discovery is a major step toward being able to “hear” the thoughts of people who can’t speak.
“If someone was completely paralyzed, or if a patient had locked-in syndrome with no movement, but the brain was still active and we could understand it well enough, we could develop devices to take advantage of that and restore communication,” said Brian Pasley, a neuroscientist at the University of California, Berkeley.
“It’s still very early,” he added. “And a lot of work still needs to be done.”
