In Episode 6 of Extreme Brains, “When Brains Pretend,” we explore why humans are wired to act, imagine, and play. With guest Craig Clyde—actor, writer, and director—we trace the roots of pretending from early ritual to modern media. We dive into how acting shapes empathy, identity, and society and examine the psychological and evolutionary power of fiction. From cave paintings to AI-generated characters, this episode uncovers how pretending helps us connect, survive, and evolve.  

Episode 5 of Extreme Brains, featuring guest Darren Davis, explores the impact of brain injuries. The discussion covers traumatic (TBI) and acquired brain injuries (ABI), their causes, symptoms, and severity. Davis shares insights on how injuries affect cognition, emotions, and daily life, highlighting struggles with identity and mental health. The episode also covers recovery options, from neuroplasticity to therapy and emerging treatments like AI-based rehab. It emphasizes prevention, resilience, and the importance of awareness and support.

What if mental illness isn’t just a glitch but an evolutionary feature? In this episode of Extreme Brains, Sam, David, and James dive deep into the fascinating world of mental health from an evolutionary perspective. Could anxiety be an ancient survival tool? Is ADHD a relic of the hunter-gatherer mind? We’ll break down key conditions, from depression to schizophrenia, and explore how once beneficial traits can become maladaptive. Plus, we’ll shift the conversation from pathology to potential—rethinking mental health through resilience, neurodiversity, and the power of human adaptability. Tune in for a mind-expanding discussion that challenges everything you thought you knew about mental illness!

Join Sam, David, and James as they unravel the mystery of temperament—the inborn traits that shape who we are before life experience even gets a chance. In this episode of Extreme Brains, the hosts dive into the science of temperament, exploring how genetics, brain chemistry, and early development influence whether we’re naturally bold, cautious, easygoing, or intense. Drawing on research from psychology, neuroscience, and behavioral genetics, they discuss why temperament matters in everything from relationships to career choices—and whether we’re stuck with the temperament we’re born with. Can temperament be changed, or is it hardwired for life? Does it give us an evolutionary advantage, or does it sometimes hold us back? And would we be better off if we had the temperament of a dog—loyal, present, and blissfully free of overthinking? Through engaging discussions, real-world examples, and plenty of humor, this episode challenges listeners to reconsider how much of their personality is under their control.

Join Sam, David, and James as they dive into the fascinating world of instincts—those deep-seated survival mechanisms that shape human behavior in ways we often overlook.
