The electrical spike activity of the small intestine at the gastroduodenal junction occurs as migrating myoelectric complexes (MMCs), initiated regularly at intervals of 90-100 min. in the adult sheep and of 20-30 min. in the neonate. This ultradian rhythm, generated by the enteric nervous system, may become identical in the adult and in the neonate, by the use of methysergide which interacts with 5-HT myenteric neurones. The results suggest a postnatal development of a serotoninergic inhibitory system, involved in the control of the basic rest-activity cycle of the small intestine.
胃十二指肠连接处小肠的电峰活动以移行性肌电复合波（MMCs）的形式出现，在成年绵羊中每隔90 - 100分钟有规律地启动，在新生羊中则为20 - 30分钟。这种由肠神经系统产生的超日节律，通过使用与5 - HT肌间神经原相互作用的麦角新碱，在成年羊和新生羊中可能会变得相同。结果表明，5 - 羟色胺能抑制系统在出生后发育，参与小肠基本静息 - 活动周期的控制。
