New brain implant can decode a person's 'inner monologue'

Scientists have developed a brain-computer interface that can capture and decode a person's inner monologue.

The results could help people who are unable to speak communicate more easily with others. Unlike some previous systems, the new brain-computer interface does not require people to attempt to physically speak. Instead, they just have to think what they want to say.
