Using Play to Rewire & Improve Your Brain | Huberman Lab Essentials

Quick Overview

Play is the most powerful portal to neuroplasticity throughout the lifespan because engaging in play triggers the release of endogenous opioids while keeping adrenaline (epinephrine) low, which opens up the prefrontal cortex to explore new contingencies and expand the brain's capacity for change.

Key Points: Play is generated through connectivity involving the periaqueductal gray (PAG), a brain stem area rich with neurons that release endogenous opioids like enkephalin. The release of these endogenous opioids allows the prefrontal cortex, responsible for executive function, to become 'smarter' by exploring different contingencies and taking on new roles. Effective play requires low amounts of adrenaline (epinephrine) and a focus/seriousness that correlates with the liberation of endogenous opioids, contrasting with high-stakes situations that inhibit the play circuitry. Play serves as contingency testing in a low-stakes environment, allowing individuals to expand their catalog of potential outcomes and discover proficiencies and limitations in social interactions. Optimal forms of play for expanding plasticity include novel forms of movement, such as dance or sports involving dynamic movements like jumping and leaping, which engage the vestibular system. Non-physical play that promotes plasticity involves activities like chess, which forces players to adopt multiple identities and rulesets within a single game, unlike rigidly linear video games. The neurobiological circuits for play do not disappear after development; biology does not waste resources, confirming the importance of play throughout adulthood for ongoing plasticity.

Context: Andrew Huberman, a professor of neurobiology and ophthalmology at Stanford School of Medicine, presents this Huberman Lab Essentials segment focusing on the biology, psychology, and utility of play for adults as well as children. The discussion centers on redefining play not merely as a childhood activity or sport, but as a critical mechanism for cognitive enhancement and lifelong neuroplasticity driven by specific neurochemical states.
