Essentials: Using Play to Rewire & Improve Your Brain

What It Covers

Andrew Huberman explains how play rewires the brain through the periaqueductal gray releasing endogenous opioids, enabling the prefrontal cortex to explore contingencies in low-stakes environments. He covers play postures, neuroplasticity mechanisms, personal play identity, and why dynamic movement activities like chess and dance expand cognitive flexibility throughout adulthood.

Key Questions Answered

• •Periaqueductal Gray Function: The brainstem area releases endogenous opioids during play, creating a neurochemical state that allows the prefrontal cortex to expand its operational algorithms. This combination of elevated opioids with low epinephrine enables exploration of different roles and contingencies without rigid executive function, fundamentally changing how the brain processes possibilities and makes predictions across all life scenarios.
• •Effective Play Requirements: True neuroplastic play requires focused attention with low stakes and minimal adrenaline. High-stakes competition or excessive concern about outcomes blocks the opioid release necessary for plasticity. The optimal state combines enough focus to engage dopamine and mild epinephrine for attention, while maintaining sufficiently low stakes to trigger endogenous opioid circuits that open learning pathways.
• •Dynamic Movement Benefits: Activities involving varied speeds, angles, and planes of motion engage the vestibular system and cerebellum to maximize plasticity. Soccer, dance, and sports requiring jumping, ducking, and lateral movements prove more effective than linear activities like running. These dynamic patterns mimic developmental play circuitry, creating stronger neuroplastic responses than repetitive, single-plane movements.
• •Chess as Multi-Role Play: Chess functions as a substrate for exploring multiple identities within one game, as each piece operates under different rules and movement patterns. Players must simultaneously adopt various roles and perspectives, unlike video games with single avatars. This multi-role engagement expands prefrontal cortex capacity more effectively than activities maintaining rigid, singular identities throughout.
• •Personal Play Identity: Four components shape adult behavior patterns: play style, personality, socioculture and environment, and economics and technology. Examining preferences between ages ten and fourteen reveals whether someone preferred competition versus cooperation, solo versus group play, and comfort with role-switching. These childhood patterns directly predict adult approaches to work relationships and social hierarchies.
