[Arterial mechanoreceptor reflex as a factor for execution of hypertensive responses to disturbing effects].
It has been shown in experiments on conscious cats and rats that arterial mechanoreceptor reflex is inhibited during averse emotional influence, and the changed reflex is a cause of elevation in arterial pressure. In one's turn the hypertension contributes to entry of blood plasma norepinephrine into brain and in this way increases the arterial baroreceptor reflex after the emotional influence is stopped. The augmentation of baroreflex promotes restoration of homeostasis after cessation of the stress situation.
