How Dopamine & Serotonin Shape Decisions, Motivation & Learning | Dr. Read Montague | Andrew Huberman

The podcast explores the multifaceted role of dopamine in motivation, learning, and behavior, challenging the common perception of it being solely a pleasure molecule. Neuroscientist Dr. Read Montague explains how dopamine fluctuations encode "temporal difference errors," driving continuous learning by comparing successive predictions, not just expectation versus reward. The conversation covers how dopamine and serotonin function in an opponent manner, influencing motivation and responses to aversive stimuli. Montague also shares insights on how SSRIs impact dopamine pathways, and discusses experiments measuring real-time dopamine and serotonin fluctuations in human brains. The discussion touches on the implications of AI, drawing parallels between algorithms in the brain and AI systems, and the potential for personalized biofeedback using nasal probes to monitor neuromodulator activity.
