WebJul 25, 2024 · The periaqueductal gray (PAG) is a key structure in the propagation and modulation of pain, sympathetic responses as well as the learning and action of defensive and aversive behaviors. Most notably, the PAG is largely responsible for descending modulation of pain perception, both in inhibition and facilitation, as pain does not depend … WebThis is because (1) many injuries simply involve both grey and white matter areas, (2) a single neuron can have its cell body and dendrites in the grey matter and an axon in the white matter, and (3) because neurons depend on their interactions with other neurons. White matter damage can cause a great deal of stress and increase the energy ...
