[Interrelations between the hypothalamus and the amygdaloid complex in the regulation of motor function of the digestive tract].
In chronic experiments on dogs, preliminary stimulation of corticomedial and parvocellular basal nuclei of amygdala augmented the motor responses of the gastro-intestinal tract to subsequent stimulation of median hypothalamic structures and weakened the inhibitory effects of posterior hypothalamic structures on motility of the digestive tract. After preliminary stimulation of the hypothalamus, the motor responses of stomach and small intestine to subsequent stimulation of corticomedial and parvocellular basal nuclei of amygdala were enhanced. The data obtained suggest existence of a complex functional hypothalamo-amygdaloid interaction, the hypothalamus with its basic mechanisms of regulation of motor function of the digestive tract playing the leading part in this interaction.
