Noga Arikha, philosopher and science humanist, explored the intersection of neurology and psychiatry in her book “The Ceiling Outside: The Science and Experience of the Disrupted Mind." In her book, Arikha described the patients she observed in a neuropsychiatry unit of Pitié-Salpêtrière hospital for 18 months. She joins us to discuss her findings and thoughts about memory, self-awareness, and identity.
