[Hypothalamic control of the myoelectric activity of the gastric antrum in rabbits during acute emotional stress].
During the experiments on the rabbits immobilized, which were undergone one day food deprivation, the influence of electric irritation of the lateral hypothalamus "hunger center" in condition of the acute emotional stress, that appears under unreinforcement of the artificially amplified hunger motivated excitation with food, which is located on the close but not reachable distance from animals, has been studied. It has been proved that increase of the alimentary motivation intensity in the process of the double-side turn-by-turn electric stimulation of digestive hypothalamic centers and appearance of uneffective food intake behaviour leads to rapid change of the bimodal patterns of the basic electric rhythm of the stomach distribution on the three-modal type distribution, which is typical for the state of hunger in condition of two days' food deprivation and also to the appearance of ectopic focus of excitations in the antral stomach part, and finally--to the development of ulcer-erosive injuries in the stomach mucosa.
