[Interrelationship between the lateral hypothalamic self-stimulation reaction and the periodic motor activity of the stomach].
In 26 dogs, self-stimulation of the dorsal portion of the lateral hypothalamus at the level of anterior parts of ventromedial nuclei inhibits completely the stomach motor activity. Self-stimulation of the lateral portion of the middle hypothalamus at the level of posterior parts of ventro--medial nuclei does not affect at all the periodic contractions of the stomach. The intensity of self-stimulation depends on phase of the stomach periodic activity: during the contractions the number of lever-pressings is by 20% higher on the average than at resting. Bilateral supra-diaphragmal vagotomy increases the self-stimulation threshold in some animals and increases the number of lever--pressings in other animals at unaltered threshold.
