Is there any physiological foundation for differentiating in between acute and chronic pain? Little is understood about the results of extended pain within the central anxious system.

The world from the Mind that stimulates the release of such hormones is the hypothalamus.[14] This influence of descending inhibition might be revealed by electrically stimulating the periaqueductal grey place in the midbrain or even the periventricular nucleus. They each subsequently project to other areas associated with pain regulation, such as the nucleus raphe magnus which also gets related afferents through the nucleus reticularis paragigantocellularis (NPG).
