WebbAs mentioned, the periaqueductal gray region is in the midbrain. It expresses a lot of opiate receptors which can be triggered by exogenous opioid pain medications or endogenous opioids synthesized naturally by the body. The three families of endogenous opioid peptides that have been identified are enkephalins, endorphins, and dynorphins.

WebbThe present study was performed to explore the effect of the galanin receptor 2 antagonist M 871on the galanin-induced antinociception in periaqueductal grey (PAG), and an involvement of Ca(2+)/calmodulin-dependent kinase II (CaMKII) in the galanin-induced antinociception. WebbHere we discovered a subset of OT neurons whose projections preferentially terminate on OT receptor (OTR)-expressing neurons in the ventrolateral periaqueductal gray (vlPAG). Using a newly generated line of transgenic rats (OTR-IRES-Cre), we determined that most of the vlPAG OTR expressing cells targeted by OT projections are GABAergic.
