This reduction ...
The brain can request the release of specific hormones or chemicals that can have analgesic effects which can reduce or inhibit pain sensation. The area of the brain that stimulates the release of these hormones is the hypothalamus. [13] This effect of descending inhibition can be shown by electrically stimulating the periaqueductal grey area ...
