[The role of oxytocin in realizing hypothalamic effects on the motor function of the digestive tract]

Chronic experiments in dogs showed that, after i.v. injection of oxytocin, the latency of activation of gastrointestinal motility by the stimulation of median hypothalamic structures was increased and inhibitory effects of posterior hypothalamic structures on the contractile activity of the digestive tract were intensified. The data obtained suggests that oxytocin facilitates the manifestation of inhibitory effects of the hypothalamus on the motor function of gastrointestinal tract.
