[Reaction of the hypothalamo-hypophyseal system of cats to stimulation of the cervical sympathetic nerve and the afferent fibers of the vagus nerve].
Data are presented on the functional morphology of the hypothalamo-hypophysial neurosecretory system of cats in stimulation of the cervical sympathetic nerve and of the afferent fibers of the vagus. Stimulation of the sympathetic nerve selectively activated the supraoptic nucleus and caused the discharge of the neurohormones from the posterior lobe of the hypophysis, whereas its infundibular portion contained much neurosecretory material. In response to the stimulation of the vagus all the portions of the neurohypophysis were released of the Gomori-positive substance; both the supraoptic and the paraventricular nucleus were activated.
