In this fascinating episode, Dr. Gabrielle Lyon talks with neuroscientist Dr. Ben Rein, PhD (author of Why Brains Need Friends), about the science of social connection, emotion, and cognitive health. Dr. Rein, an expert in neurobiology and psychedelic research, reveals the cutting-edge studies that explain why loneliness is as damaging as smoking and how our digital world is affecting our brain's ability to connect.

They discuss the neurochemistry of love, the controversial use of MDMA in therapy, and whether AI can ever truly replace human intimacy. This conversation provides an essential look at the biological drivers of happiness, performance, and long-term brain health.
