Forestomach motility in adult sheep when reflex reticular groove closure is provoked by 10 ml of 10% copper sulphate solution was studied electromyographically. Rumen and omasum motility disappeared with the administration of the stimulant, while some muscular activity of the reticulum was always present but was manifested by monophasic, more frequent and weaker contractions than before stimulation; between these contractions very frequent small discharges appeared in the electromyogram from the reticulum. Cyclic activity of the forestomach reappeared 3 to 5 min later and returned gradually to normal. The functional significance of these findings is discussed.
通过肌电图研究了成年绵羊在经10毫升10%硫酸铜溶液诱发反刍网状沟关闭时的前胃运动。给予刺激物后，瘤胃和瓣胃运动消失，而网胃始终存在一些肌肉活动，但表现为单相、比刺激前更频繁且更弱的收缩；在这些收缩之间，网胃的肌电图中出现非常频繁的小放电。前胃的周期性活动在3至5分钟后重新出现，并逐渐恢复正常。讨论了这些发现的功能意义。
