Since the centrifugal inhibitory effect of acupuncture on nociceptors wasfound in 1982

Electrical stimulation of the lateral hypothelamic area could inhibitthe peripheral noxious afferents through the adrenal gland-sympathetic system

indicating that the lateral hypothalamic area is one of the centres originatingthe centrifugal inhibitory effect on nociceptors.
