Characterization of descending inhibition and facilitation from the nuclei reticularis gigantocellularis and gigantocellularis pars alpha in the rat
M Zhuo, GF Gebhart - Pain, 1990 - Elsevier
Descending influences on the spinal nociceptive tail-flick (TF) reflex produced by focal
electrical stimulation and glutamate microinjection in the nuclei reticularis gigantocellularis
(NGC) and gigantocellularis pars alpha (NGCα) were examined and characterized in rats
lightly anesthetized with pentobarbital. Both inhibition and facilitation of the TF reflex were
produced by electrical stimulation at identical sites in the NGC/NGCα; glutamate
microinjection only inhibited the TF reflex. The chronaxie of stimulation for inhibition of the …
