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

About this video

In this Essentials episode, Huberman explains the biology and utility of play. He presents play as contingency testing — exploring ‘if I do this, what happens?’ — in low-stakes environments where it feels safe to try different roles. Huberman describes the periaqueductal gray, a brainstem area rich in neurons releasing endogenous opioids, as key: he explains that this opioid release lets the prefrontal cortex run more operations, take on roles and make predictions more flexibly. He adds that genuine play also requires low adrenaline, since high adrenaline inhibits playfulness. Huberman argues play circuits persist throughout life, that development is one long arc, and that adult play expands creativity, flexibility and neuroplasticity rather than being merely fun or childish.

Key takeaways

• Huberman defines play as contingency testing in low-stakes environments.
• Huberman describes endogenous opioid release from the periaqueductal gray as enabling more flexible prefrontal function during play.
• Huberman explains that low adrenaline is required for genuine play, as high adrenaline inhibits playfulness.
• Huberman argues play circuits are retained across the lifespan and support neuroplasticity in adults.
• Huberman presents role play as expanding the brain’s catalog of possible behaviors and predictions.
