This is your brain on communication

From http://ideas.ted.com/this-is-your-brain-on-communication/

“We scanned the brains of five listeners while they were at rest and waiting for the storyteller to begin, and saw that although their auditory cortices were all active, their responses were very different and not in sync with one another. However, immediately as the story started, we saw something amazing happen. Suddenly, we saw the responses in all of the subjects begin to lock together and go up and down in a similar way.”
