Psychologists report for the first time that the temporoparietal junction (TPJ) and dorsomedial prefrontal cortex (DMPFC) brain regions are associated with the successful spread of ideas, often called 'buzz.'

When you post a story to your Facebook page, or forward a funny meme, what's going through your head? Researchers at UCLA have been searching for the answer to that elusive question of why people share ideas or why things get "buzz."

Matthew Lieberman, professor of psychology and of psychiatry at UCLA and author of the upcoming book "Social: Why Our Brains Are Wired to Connect," joins the show to explain.
