Psychologist Kimberley Wilson and Dr Xand van Tulleken take a journey around the human body, asking what it can tell us about our innate capacity for change. In this episode, they explore serotonin - a chemical involved in everything from sleep to bowel function, appetite to blood clotting.

Xand and Kimberley find out why serotonin鈥檚 reputation as the 鈥渉appy chemical鈥� is misleading, explore the interaction between serotonin and dopamine in sex drive, and hear about new approaches to treating depression using psychoactive drugs.
