The endocannabinoid system in the rat dorsolateral periaqueductal grey mediates fear-conditioned analgesia and controls fear expression in the presence of nocicpetive tone
(Wiley, 2011)
Background and purpose: Endocannabinoids in the midbrain periaqueductal grey (PAG) are involved in modulating nociception and unconditioned stress-induced analgesia, however, their role in fear-conditioned analgesia (FCA) ...
Genotype-dependent responsivity to inflammatory pain: A role for TRPV1 in the periaqueductal grey
(Elsevier, 2016-08-09)
Negative affective state has a significant impact on pain, and genetic background is an important moderating influence on this interaction. The Wistar-Kyoto (WKY) inbred rat strain exhibits a stress-hyperresponsive, ...
Effects of direct periaqueductal grey administration of a cannabinoid receptor agonist on nociceptive and aversive responses in rats
(Elsevier, 2003-07-31)
The analgesic potential of cannabinoids may be hampered by their ability to produce aversive emotion when administered systemically. We investigated the hypothesis that the midbrain periaqueductal grey (PAG) is a common ...
Supraspinal transient receptor potential subfamily V member 1 (TRPV1) in pain and psychiatric disorders
(Karger, 2015)
The transient receptor potential subfamily V member 1 (TRPV1) belongs to the diverse transient receptor potential (TRP) family of cation channels. It was first characterized in primary afferent fibres as a receptor for ...
