Passive mobilization may stimulate the SNS and activate the descending pain inhibitory mechanism which increases sympathetic activity and decreases pain due to the release of noradrenaline from the dorsal periaqueductal grey
Citronellol reduces orofacial nociceptive behaviour in mice--evidence of involvement of retrosplenial cortex and periaqueductal grey
During the resting brain scan, the women consuming probiotics showed greater connectivity between a key brainstem region known as the periaqueductal grey
and cognition-associated areas of the prefrontal cortex.
A role of periaqueductal grey
NMDA receptors in mediating formalin-induced pain in the rat.
Associated neurobiological structures and functions associated with the FFFS are the periaqueductal grey
, medial hypothalamus, and amygdala, and serotonergic inputs into these structures.
