[Maintaining hypertension in negative emotional exposures as one of the functions of the baroreceptor reflex].
Changes in the heart rate and blood pressure induced by different emotiogenic influences were studied in rats with intact and denervated baroreceptor afferents of the carotid sinuses and aortic arch. Aversive emotiogenic stimuli failed to induce hypertension in rats with denervated baroreceptor areas, while self-stimulation in these rats caused a profound rise in arterial pressure. It is concluded that maintenance of hypertension induced by aversive emotiogenic influences is a manifestation of baroreceptor reflex.
