Spike potential activity of the jejunum was recorded from chronically implanted electrodes in conscious sheep. The activity was summed at 20-sec intervals before, during, and after induction of diarrhea, small-bowel obstruction, and after nerve section. Sheep on a normal diet regimen exhibited migrating myoelectric complexes at a frequency of 18/24 hr. These complexes displayed irregular and regular activities which occupied 67% of the recording time. A common pattern observed during the manipulations was disorganization of the motor profile. The normal pattern was replaced by continuous spiking activity followed in many cases by total quiescence. After vagotomy the complexes still occurred but the duration of irregular spiking activity was decreased. These experiments suggest that the migrating myoelectric complex acts as a regulating factor and suggests that the ratio of irregular to regular activity is dependent on the influence of extrinsic nerves.
在清醒绵羊身上，通过长期植入的电极记录空肠的锋电位活动。在诱发腹泻、小肠梗阻期间及之后，以及神经切断后，每隔20秒对活动进行一次汇总。采用正常饮食方案的绵羊以18/24小时的频率表现出移行性肌电复合波。这些复合波表现出不规则和规则的活动，占记录时间的67%。在操作过程中观察到的一个常见模式是运动模式紊乱。正常模式被持续的锋电位活动所取代，在许多情况下随后是完全静止。迷走神经切断术后，复合波仍然出现，但不规则锋电位活动的持续时间缩短。这些实验表明，移行性肌电复合波起调节因子的作用，并表明不规则与规则活动的比例取决于外在神经的影响。
