In this episode of Talk Nerdy, Cara is joined by Dr. Sidarta Ribeiro, professor of neuroscience and founder of the Brain Institute at the Federal University of Rio Grande do Norte in Natal, Brazil. They talk about his new book, "The Oracle of Night: The History and Science of Dreams." Topics include what dreaming is (and isn't), why we dream, and what contemporary neuroscience, biochemistry, and genetics can tell us about this ancient evolutionary experience.
