To investigate the effect of microinjection of motilin into ventral medail hypothalamus (VMH) or intracerebroventricle (icv) on gastric motility, extracellular unit responses of dorsal vagal complex (DVC) in anesthetized rats and gastric motility of conscious rats were recorded. The results are as follows. (1) The firing rate of gastric distention related neurons in DVC was modified. (2) VMH and icv administration of motilin induced obvious enhancement in gastric motility. (3) The effect of motilin on gas...
