Periaqueductal Gray
A brain structure implicated in a wide range of innate behaviors, including pain, fear, panic, freezing, and mating, acting as a 'telephone switchboard' for routing information.
Videos Mentioning Periaqueductal Gray

Using Play to Rewire & Improve Your Brain
Andrew Huberman
A brain stem area rich with neurons that make endogenous opioids, which are released during play to 'dope up' the system slightly, allowing the prefrontal cortex to explore different roles and contingencies.

Erasing Fears & Traumas Based on the Modern Neuroscience of Fear
Andrew Huberman
A brain area that contains neurons capable of triggering freezing behavior and releasing endogenous opioids, which numb pain, as part of the threat response.

The Biology of Aggression, Mating, & Arousal | Dr. David Anderson
Andrew Huberman
A brain structure implicated in a wide range of innate behaviors, including pain, fear, panic, freezing, and mating, acting as a 'telephone switchboard' for routing information.

Understanding & Controlling Anger & Aggression
Andrew Huberman
A brain structure connected to the VMH, involved in downstream circuits for aggressive behaviors like biting and limb swinging, and housing neurons that produce endogenous opioids.

Using Light (Sunlight, Blue Light & Red Light) to Optimize Health
Andrew Huberman
A region of the midbrain rich in neurons that release endogenous opioids, contributing to pain tolerance; activated by light landing on the eyes.
