Rebecca Saxe from MIT giving a short talk about how we think about other people's thoughts and which region of the brain is involved in the process. The Right Temporal Parietal Junction is a small area, above and behind the right ear. Its only task is to think about other people's thoughts. Very interesting stuff! It apparently is of great interest to the Pentagon too, but Rebecca says she won't take their calls.
