    The Comfort of the Known - Why We Stay Stuck

    Why do we stay in patterns that hurt us? Why do we return to familiar anger, destructive relationships, or self-defeating habits even when we logically know better? In this episode, we explore the neuroscience of why the brain mistakes familiarity for safety - and what it takes to actually change. In This Episode: Why "knowing better" doesn't equal "doing better"The two minds competing inside your brain (and which one usually wins)How your hippocampus keeps you stuck in the familiarThe aversion amplifier: why change feels dangerous even when it's goodFive science-backed conditions for creating lasting change SOURCES REFERENCED: Brain Systems & Memory: Dual hippocampal memory systems (associative vs. predictive coding) - optogenetic study in rats demonstrating separate memory pathways for familiarity and navigation Default Mode Network: DMN activation patterns in depression and rumination - increased self-referential processing maintains negative narratives Aversion & Threat Processing: Interpeduncular nucleus (IPN) circuit amplifies aversive experiences - isolated brainstem pathway that intensifies discomfort without triggering general anxiety Cognitive Flexibility: Brain signal variability correlates with cognitive flexibility - higher variability in inferior frontal junction predicts better task-switching ability Model Arbitration: Amygdala's role in arbitrating between habit-based and goal-directed learning systems Quote: Scott Galloway: "It's very difficult to read the label from inside the bottle"

    Nutrition and gut health effects on the brain

    Your gut is talking — and your brain is listening. Discover how diet, microbiota, and even fasting reshape your brain chemistry, mood, and cognition in this deep dive into the gut-brain connection. Your gut is talking to your brain — and your brain is listening. In this episode of The Cognitive Performer, we explore the gut-brain axis — the communication highway connecting your digestive system and your mind. Discover how trillions of microorganisms influence your mood, focus, memory, and long-term brain health. We’ll look at how diet shapes your microbiome, why certain bacteria can act like microscopic pharmacists, and what dietary patterns best protect cognitive function. From the serotonin-shaping power of Roseburia intestinalis to the fasting-linked boost in microglial cleanup, this episode unpacks the real neuroscience behind “gut feelings.” Key TakeawaysRoughly 90 % of the vagus-nerve signals run from gut → brain, not the other way around.The gut microbiome produces neurotransmitters such as serotonin, dopamine, and GABA that directly influence mood and cognition.Stress diverts tryptophan from serotonin production toward inflammation — but beneficial bacteria can reverse that shift.Mediterranean, DASH, and MIND diets consistently support brain health by nourishing diverse gut bacteria.Alternate-day fasting reshapes gut microbes and improves microglial function, translating into measurable cognitive gains.Building cognitive reserve through learning, social connection, movement, and sleep can cut dementia risk nearly in half.

    Fear Extinction: How to Rewire Your Brain for Resilience

    Think you're stuck with an anxious, stressed brain? Think again. In this episode of The Cognitive Performer, Marco explores the neuroscience of fear extinction - your brain's natural ability to unlearn stress responses and build resilience instead. Discover why stress literally rewires your neural circuits, how fear conditioning keeps you stuck in anxiety loops, and the specific, science-backed techniques you can use to intentionally reshape your brain's stress response. What You'll Learn: The difference between classical and operant conditioning (and why fear responses use the classical type)How chronic stress flattens your cortisol rhythm and damages neural connectionsWhy your amygdala hijacks your prefrontal cortex during stress responsesThe three-step process of fear extinction and how it creates competing memoriesWhy cyclic sighing outperforms mindfulness and box breathing for nervous system regulationHow sleep actively rewires your brain through synaptic homeostasisPractical tools for building antifragility - getting stronger from stress instead of just surviving it Key Topics: Fear extinction, neuroplasticity, stress response, amygdala function, prefrontal cortex, cortisol regulation, classical conditioning, synaptic depression, parasympathetic activation, brain network connectivity, cognitive flexibility, antifragility Practical Techniques Covered: 90-second cyclic sighing protocol for nervous system resetMindfulness practices that break rumination loopsMovement strategies for neuroplasticity and BDNF productionSleep optimization for emotional memory processingBuilding safe exposure routines for stress triggers Perfect for: Voice actors, performers, creatives, anyone dealing with performance anxiety, stress management, or wanting to understand how to work with their brain instead of against it. Research-Backed: All techniques discussed are supported by recent neuroscience studies from 2021-2025, with specific focus on fear extinction mechanisms, large-scale brain network changes, and evidence-based interventions for stress resilience.

    Dopamine: The Misunderstood Molecule

    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.

    Navigating Imposter Syndrome: Evidence-Based Strategies for Voice Actors

    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.

    The Science of Performance Anxiety

    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. Below are the links to research materials mentioned in this episode.
