What is sleep? Why do we dream? And what goes on in sleeping brains—from the tiny fruit fly’s to ours? In this program, Alan Alda talks with top sleep researchers and also highlights the winners of the 2015 Flame Challenge, in which video and written explanations of sleep were judged by 20,000 eleven year-olds.
This program is in association with the Flame Challenge, an annual contest held by The Alan Alda Center for Communicating Science at Stony Brook University.
