[Critical study of electric activity of the small intestine in the dog]

Thanks to a cross-circulation, the authors caused to survive in the abdomen of a sacrificed dog, the whole of the small intestine, the motor activity of which was analysed by electro-enterography. This experimental preparation thus eliminates polygraphic recordings of all potential variations outside the small intestine, e.g. stomach, colon, diaphragm, muscle, myocardium. One thus obtains very pure tracings of the variations of potential originating in the small intestine, recorded from bipolar serous intestinal electrodes, they show the activity of the small intestine, consisting of a permanent basal electric rhythm on which are grafted spikes contemporary of motor phenomena. In the abdominal skin there were recorded only a cutaneous slow wave which was contemporary with the deep motor phenomena.
