Biological Systems Mechanism Map
Brain & Hypothalamic-Pituitary-Adrenal (HPA) Axis
The unexpected comedic stimulus triggers a rapid dopaminergic surge in the nucleus accumbens and prefrontal cortex. This abruptly overrides the amygdala's chronic threat loop, inhibiting corticotropin-releasing hormone (CRH) synthesis.
