Neurons in the pontomedullary raphe magnus (RM) and adjacent nucleus reticularis
paragigantocellularis pars α (NRPGα) are thought to participate in the modulation of spinal …

The nucleus raphe magnus (NRM) is an important descending inhibitory system for pain
transmission. We tested whether clonidine, an alpha 2-adrenergic agonist, and yohimbine …

Publisher Summary This chapter focuses on the nociceptive modulatory role of neurons in
the pontomedullary raphe magnus (RM) and the adjacent nucleus reticularis …

The nucleus raphe magnus (NRM) is an important descending pain inhibitory system. We
postulated that the analgesic action of supraspinally administered opiates results from …

The effects of isoflurane and halothane on the behavior of mesencephalic reticular neurons
in the rat were studied by long-term extracellular microelectrode recording. Both anesthetics …

In urethane-anesthetized rabbits the effects of periaqueductal gray (PAG) and nucleus raphe
magnus (NRM) stimulation on the spontaneous and the noxious-evoked activity of the lateral …

The dorsal raphe (DR) nucleus is a system of nuclei in the midline of the lower brainstem,
which is considered one of the most important nuclei in the modulation of pain in the central …

The organization in the brain stem of descending inhibitory control of spinal nociceptive
information was studied in anesthetized, paralyzed cats by quantitatively evaluating the …

Focal electrical stimulation in the midbrain periaqueductal gray (PAG) or medullary nucleus
raphe magnus (NRM) inhibits spinal nociceptive transmission and nociceptive reflexes. The …

The organization in the brainstem of descending pathways of spinal inhibition was
examined in the lightly pentobarbital-anesthetized rat. Thresholds for focal electrical …
