Prefrontal Cortex: What We Knew Then

Dr. Adele Diamond is one of the world’s most influential developmental cognitive neuroscientists and a pioneer in our understanding of executive functions — the brain’s core control processes that shape attention, self-regulation, problem-solving, and goal-directed behaviour.Her groundbreaking research was the first to show that the prefrontal cortex is active in infants, transforming how we understand child development and reshaping clinical treatment for ADHD and PKU worldwide. She’s also led the charge in redefining education, proving that joy, movement, play, and emotional connection aren’t luxuries — they’re neuroscience-backed necessities.

Expect to learn what executive functions really are and why they matter for everything from school performance to lifelong happiness, the overlooked role of the prefrontal cortex in ADHD, how dopamine operates very differently in this brain region, the crucial (and often missed) distinction between types of ADHD, why some kids are misdiagnosed when they’re actually suffering from trauma, why psychostimulants can backfire and how we might be overprescribing the wrong doses, why martial arts might outperform cognitive training, how childhood stress reshapes brain wiring, the profound importance of early encouragement and self-concept, how AI and smartphones are degrading our cognitive systems, why social-emotional connection is a prerequisite for learning, and what Adele believes schools are still getting tragically wrong — even today.This is an episode about rewiring how we think about attention, emotion, learning, and what it means to help human beings thrive.
