Investigators have demonstrated pressor areas in the medullas of various species. The present study precisely localized the pressor area in the caudal medulla of the rat and determined its projections to the caudal and rostral ventrolateral medulla. The caudal medulla first was mapped grossly in rats with injections (30 nl) of glutamate (30-, 15-, and 7.5-nmol doses) placed 0.5, 1.0, and 1.5 mm...
The transient receptor potential vanilloid-1 (TRPV1) receptor is involved in peripheral and spinal nociceptive processing and is a therapeutic target for pain. We have shown previously that TRPV1 in the ventrolateral periaqueductal gray (VL-PAG) tonically contributes to brain stem descending antinociception by stimulating glutamate release into the rostral ventromedial medulla and off neuron ac...
Transient receptor potential vanilloid type 1 (TRPV1) receptor is a non selective ligand-gated cation channel activated by capsaicin, heat, protons and endogenous lipids termed endovanilloids. As well as peripheral primary afferent neurons and dorsal root ganglia, TRPV1 receptor is also expressed in spinal and supraspinal structures such as those belonging to the endogenous antinociceptive desc...
Background and Purpose Activation of the defence reaction inhibits baroreflex response via intermediate rostro-ventromedial medulla (B3 raphé) nucleus tractus solitarius (NTS). Our aim was to determine whether how inhibition, induced by disinhibition rostral cuneiform (part pathway), involves 5-HT neurons in B3 5-HT3 receptors NTS. Experimental Approach We performed immunohistochemistry anatomi...
The orofacial region is a major focus of chronic neuropathic pain conditions characterized by primary hyperalgesia at the site of injury and secondary hyperalgesia outside the injured zone. We have used a rat model of injury to the maxillary branch (V2) of the trigeminal nerve to produce constant and long-lasting primary hyperalgesia in the V2 territory and secondary hyperalgesia in territories...
