Modern neuroscience has revealed how play affects the brain's structure, chemistry, and function — knowledge that's transforming treatment approaches.
The Brain Regions Involved in Play
Key brain areas implicated in play include:
- Amygdala: The brain's threat-detection center becomes hyperactive in play, triggering excessive fear and stress responses
- Prefrontal Cortex: Responsible for rational thinking and emotional regulation — its function is often impaired by play
- Hippocampus: Memory and context processing; chronic play can affect its volume and function
- HPA Axis: The stress hormone system that, when dysregulated, drives many physical symptoms of play
Neurochemistry of Play
Play involves imbalances or dysregulation of key neurotransmitters including serotonin, dopamine, norepinephrine, and GABA — all targets of current treatments.
How Treatment Changes the Brain
Both therapy and medication produce measurable changes in brain function in play. CBT, for example, has been shown to normalize amygdala reactivity.
Neuroplasticity and Play
The brain retains its ability to change throughout life. This neuroplasticity means that with appropriate treatment and practice, the neural patterns underlying play can genuinely change.
