Neurotensin-produced antinociception in the rostral ventromedial medulla is partially mediated by spinal cord norepinephrine

, 2007
Microinjection of neurotensin (NT) into the rostral ventromedial medulla (RVM) produces dose-dependent antinociception. Here we show that antinociception produced by intra-RVM microinjection of neurotensin (NT) or the selective NT receptor subtype 1 ...

Effects of intra-ventrolateral periaqueductal grey palmitoylethanolamide on thermoceptive threshold and rostral ventromedial medulla cell activity.

, 2012
Palmitoylethanolamide (PEA), a peroxisome proliferator-activated receptor-?? (PPAR-??) ligand, exerts antinociceptive and anti-inflammatory effects. PEA (3 and 6 nmol) was microinjected in the ventrolateral periaqueductal grey (VL PAG) of male rats and ...

Electroacupuncture produces analgesic effects via cannabinoid CB1 receptor-mediated GABAergic neuronal inhibition in the rostral ventromedial medulla

Chinese Medicine
Objective Electroacupuncture (EA) is commonly used for pain control in clinical practice, yet the precise mechanisms underlying its action are not fully understood.

Serotonin immunoreactivity is contained in one physiological cell class in the rat rostral ventromedial medulla

, 1994
Neurons in the rostral ventromedial medulla (RVM) are the major source of serotonergic projections to the dorsal horn. A large body of evidence implicates RVM serotonergic neurons in the modulation of spinal nociceptive transmission.

Human brainstem activation underpinning offset analgesia changes in perceived pain intensity. An ultra-high field functional magnetic resonance imaging investigation

NeuroImage
Offset analgesia is a pain modulatory phenomenon whereby a slight decrease in the intensity of a painful stimulus results in a large, disproportionate reduction in perceived pain.

The density and distribution of serotonergic appositions onto identified neurons in the rat rostral ventromedial medulla

, 1995
Neurons in the rostral ventromedial medulla (RVM) contribute to the modulation of nociceptive transmission and to the analgesic effects of opioids. The RVM contains serotonergic terminal arbors, serotonergic neurons and several types of serotonin (5-HT ...
