Chris and Xand continue their conversation about dopamine with Masud Husain, Professor of Neurology & Cognitive Neuroscience at the University of Oxford.

Welcome to What’s Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken untangle the confusion around every aspect of our health and wellbeing.In this episode, they’re diving into dopamine – one of the most talked-about chemicals in modern wellness culture. But what is dopamine, really? What role does it play in pleasure, motivation, learning, and movement? And how accurate are ideas like “dopamine hits”, “dopamine detoxes”, or being “addicted to dopamine”?Chris and Xand speak to Masud Husain, Professor of Neurology & Cognitive Neuroscience at the University of Oxford, to cut through the myths and find out what dopamine does, what it doesn’t do, and why understanding it properly might change the way we think about our behaviour and our brains.If you want to get in touch, you can email us at whatsupdocs@bbc.co.uk or WhatsApp us on 08000 665 123.Presenters: Drs Chris and Xand van Tulleken Guest: Professor Masud Husain Producer: Maia Miller-Lewis Executive Producer: Rami Tzabar Editor: Jo Rowntree Researcher: Grace Revill Tech Lead: Reuben Huxtable Social Media: Leon Gower Digital Lead: Richard Berry Composer: Phoebe McFarlane Sound Design: Melvin RickarbyAt the BBC: Assistant Commissioner: Greg Smith Commissioning Editor: Rhian RobertsA Loftus Media production for BBC Radio 4

Welcome to What’s Up Docs?, the podcast where doctors and identical twins Chris and Xand van Tulleken confront the confusion around every aspect of our health and wellbeing.In this episode, they’re asking why beliefs about our bodies are so powerful? We often think of belief as something soft – just ideas in our heads. But beliefs can shape how we experience pain, how we heal, and even how societies behave. In health, they can influence whether treatments work and how symptoms are felt. So what actually are beliefs? Why do we them, and how do they form? And can changing what we believe about our bodies actually change how we feel?To help answer these questions, Chris and Xand are joined by Ryan McKay, Professor of Psychology at Royal Holloway, University of London, and an expert on the psychology of belief.If you want to get in touch, you can email us at whatsupdocs@bbc.co.uk or WhatsApp us on 08000 665 123.Presenters: Drs Chris and Xand van Tulleken Guest: Professor Ryan McKay Producer: Maia Miller-Lewis Executive Producer: Rami Tzabar Editor: Jo Rowntree Researcher: Grace Revill Tech Lead: Reuben Huxtable Social Media: Leon Gower Digital Lead: Richard Berry Composer: Phoebe McFarlane Sound Design: Melvin RickarbyAt the BBC: Assistant Commissioner: Greg Smith Commissioning Editor: Rhian RobertsA Loftus Media production for BBC Radio 4
