In this episode, host Dr. Mike Hart welcomes neuroscientist and author Dr. Ben Rein to discuss his new book, 'Why Brains Need Friends: The Neuroscience of Social Connection.' Dr. Rein shares his journey in neuroscience, his research on autism and MDMA, and his pivot towards science communication. They delve into the devastating effects of loneliness, comparing its impact on mortality to smoking 15 cigarettes a day, and explore why human connections are critical for our brain health. Dr. Rein also discusses the benefits of having pets, the intricate balance of social interactions across a lifespan, the effects of MDMA on feelings of connection, and the role of oxytocin in social bonding. This episode provides a deep dive into the science behind social interactions, offering actionable insights to improve mental health and wellbeing.

Dr. Ben Rein is a neuroscientist, educator, and science communicator whose work explores the biology of human connection, empathy, and social behavior. With a Ph.D. in neuroscience and postdoctoral research at Stanford University, Dr. Rein has studied everything from the neural underpinnings of autism spectrum disorder to how MDMA (ecstasy) enhances empathy in the brain.
