Algorithm Reads Minds, Translates Brain Activity Into Words
Scientists have picked up fragments of people’s thoughts by decoding the brain activity caused by words that they hear. The remarkable feat has given researchers fresh insight into how the brain processes language, and raises the tantalizing prospect of devices that can return speech to the speechless.
Though in its infancy, the work paves the way for brain implants that could monitor a person’s thoughts and speak words and sentences as they imagine them. Such devices could transform the lives of thousands of people who lose the ability to speak as a result of a stroke or other medical conditions.
