title: Nucleus raphe obscurus (nRO) influences vagal control of gastric motility in rats.
abstract: Because the nucleus raphe obscurus (nRO) maintains a direct connection with the dorsal vagal complex in the medulla, this nucleus has the potential to influence vagal control of gastric function. Both electrical- and glutamate-induced activation of the nRO were found to enhance gastric motility and tone in the rat. The gastric responses to nRO stimulation were abolished by peripheral muscarinic blockade.
