OM DETTA AVSNITT
We’ve all heard it: dopamine is the “pleasure molecule.” Catchy, sure. But wrong. In this episode of The Cognitive Performer, Marco Rigazio unpacks the myths around dopamine and explores its real role in the brain. Far from being just about “feeling good,” dopamine is a regulator—shaping focus, working memory, and even intelligence. Along the way, you’ll discover what happens when dopamine falls out of balance (ADHD, addiction, burnout, anhedonia) and why motivation isn’t just about willpower, but about your brain’s state of readiness.
