Periaqueductal Grey AKA PAG, Central GreyΩ
A cluster of neurons in the human brain peripheral to the cerebral aqueduct. PAG takes the form of gray matter and plays a central function in analgesia (pain reduction), abstract mania (see: apeirophobia), and autonomic responses to threatening stimuli. The PAG's high concentration opioid receptors are activated by many narcotics including morphine, hydrocodone, and oxycodone. Natural PAG opioid stimulants include waves of extreme nostalgia, teenage fellatio, and Dharmic transcendence of self. The PAG plays a central role in "fight or flight response": extreme and stimulation of the area due to real (or imagined) threat can lead to a misleadingly lackadaisical posture known as quiescence [1]. Overstimulated PAG can become activated pathologically resulting in dysregulation - a state commonly associated with the development of various forms of psychosis, most notably induced schizophrenic bicameralism.
