Essentials: Using Play to Rewire & Improve Your Brain
Huberman Lab Podcast Recap

What Happened
Andrew Huberman, professor of neurobiology and ophthalmology at Stanford School of Medicine, explains how play is intricately linked with various brain areas, particularly the periaqueductal gray (PAG). This brain region is dense with neurons that release endogenous opioids like enkephalin, which are crucial for creating the pleasurable sensations associated with play.
Play provides a safe environment for exploring different roles and scenarios, which is vital for both children and adults. It evokes small amounts of opioid release that aid the prefrontal cortex in considering diverse outcomes and possibilities. This engagement in low-stakes exploration enhances intellectual and social capabilities, enriching a person's life.
Role play is highlighted as a tool for establishing social hierarchies and expanding the operations of the prefrontal cortex. This process is significant for prediction and adaptation, as it fosters neuroplasticity by engaging the brain in novel behaviors and interactions. Effective play involves low adrenaline levels and high endogenous opioid levels, which support brain plasticity.
Huberman discusses the importance of dynamic movements, such as those found in dance or sports, which stimulate the vestibular system and cerebellum. These movements integrate visual information and are beneficial for learning and brain adaptability. The vestibular system's role in neuroplasticity is emphasized, showing how physical activities can enhance cognitive functions.
Chess is mentioned as a game that reflects a child's inner world, promoting neuroplasticity by requiring players to assume multiple roles. Unlike video games, where players often stick to one character, chess requires a fluid identity, which is beneficial for brain development. Huberman cites a 2017 paper that underscores chess's value in educational settings.
The episode concludes by examining how personal play identity, shaped by factors such as personality, socio-culture, and environment, influences adult interactions. Huberman asserts that play habits developed between ages 10 and 14 can have lasting effects on adult behavior. He stresses that development is a lifelong process, and play remains crucial for maintaining cognitive flexibility.
Key Insights
- Play engages multiple brain areas, with the periaqueductal gray (PAG) playing a central role. The PAG is rich in neurons that release endogenous opioids, which create pleasurable sensations during play and facilitate exploration.
- Engaging in play helps the prefrontal cortex explore various roles and outcomes in a low-stakes environment. This process enhances intellectual and social capabilities by fostering a broad range of potential outcomes.
- Dynamic movements, such as those in dance or sports, engage the vestibular system and cerebellum, supporting neuroplasticity. These activities integrate visual and physical information, which is crucial for learning and adaptation.
- Chess is highlighted as a game that promotes neuroplasticity by requiring players to assume multiple roles. Unlike video games that typically involve a single avatar, chess encourages a flexible identity that benefits brain development.
