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.

Ever record take after take and still feel unsure which one was right?

It might not be a creative block. It could be decision fatigue.

In this episode of The Cognitive Performer, we break down what really happens when your brain gets overloaded — and how it quietly shapes the choices you make during creative work.

You’ll learn:

• How small, invisible decisions stack up during a session
• What fatigue does to your planning, flexibility, and creative flow
• Why defaulting to “what usually works” isn’t always a good thing
• How to spot the signs of mental drain before it tanks your performance
• Simple science-backed ways to protect your energy and output

Thanks for listening — and don’t miss next month’s episode on dopamine: the buzzword, the brain chemical, and the reality behind the hype.

In this special Q&A episode, Marco answers fascinating questions from fellow voice actors about the brain and performance. Discover why people think so differently (it's actual brain wiring, not just personality), what dreams really do for your brain, and the surprising science behind "manifestation." Plus: where creativity actually comes from, what happens in your brain during those amazing "aha moments," and why exercise might be the single best thing you can do for brain health.

Topics covered: Analytical vs. holistic thinking • Dream science • Positive/negative thinking patterns • Brain aging and adaptation • The neuroscience of creativity • "Eureka moment" brain chemistry • Exercise effects on the brain

Questions from: Norm Izard (vocalnorm.com) • Monique Mosher • Erin Cox

Imposter syndrome, a pervasive psychological phenomenon, is the focal point of our discourse today. We delve into the intricate interplay between the mind and body as we explore this condition that afflicts many, particularly within creative professions. By elucidating the underlying neuroscience, we aim to demystify the experiences associated with imposter syndrome, ultimately equipping our listeners with empirically supported strategies to manage its effects. Throughout this episode, we will examine how these feelings manifest, their neurological triggers, and the correlation with maladaptive perfectionism. As we navigate through this complex landscape, we shall also highlight effective interventions derived from contemporary research, thereby fostering a deeper understanding of this common yet often misunderstood experience.

In this episode of The Cognitive Performer, I dive into the fascinating neuroscience behind performance anxiety and discuss how it specifically affects voice actors. Learn why your body responds the way it does during high-pressure situations, how anxiety impacts your vocal performance, and why trying harder often makes things worse.

I explore the surprising "paradox of choking" and understand the critical difference between helpful performance arousal and debilitating anxiety. You'll discover evidence-based techniques to regulate your nervous system, including specific breathing patterns, cognitive reframing strategies, and a complete pre-recording routine you can implement immediately.

Based on cutting-edge research from performance psychology and neuroscience, this episode provides practical tools to transform anxiety from your enemy into your ally. Whether you're dealing with audition nerves, session jitters, or that critical inner voice that sometimes shows up in the booth, you'll learn how to perform at your best, even under pressure.
