UC Berkeley researchers decode brain waves

Researchers at U.C. Berkeley are working on a project that may allow doctors to communicate with patients who've lost the ability to speak.

Neuroscientists used CAT scans to decode electrical activity in the brain's temporal lobe, while a test subject listened to normal conversation.

Based on the correlation between sound and brain activity, they were then able to reconstruct imagined conversations.

The researchers say there's evidence that hearing a sound and imagining a sound activate similar areas of the brain.
