The Mind can ask for the release of specific hormones or substances that could have analgesic consequences which could minimize or inhibit pain sensation. The realm from the Mind that stimulates the discharge of such hormones would be the hypothalamus.[fourteen] This influence of descending inhibition is usually shown by electrically stimulating the periaqueductal gray space of the midbrain or even the periventricular nucleus. They equally in turn venture to other parts involved in pain regulation, like the nucleus raphe magnus which also gets related afferents through the nucleus reticularis paragigantocellularis (NPG).
