In 1953, a botched lobotomy left 27-year-old Henry Molaison unable to create new long-term memories. This hour, we’ll talk about how scientists seized on the opportunity to study his brain – and how that research has provided vital information about how human’s store information. We’ll be joined by Luke Dittrich, author of “Patient H.M.: A Story of Memory, Madness, and Family Secrets” (Random House).
