[An analysis of the mechanisms enhancing arterial baroreceptor reflexes during noradrenaline infusion]

In cats-recipients with cut vagosympathetic trunks and hemodynamically isolated carotid sinuses, the latters were perfused with the blood from a cat donor. Noradrenaline infusion did not change the electrical activity of the renal nerve and induced an inhibition of the activity in high perfusion pressure. Noradrenaline seems to induce a short-term enhancement of arterial baroreflexes and to potentiate the effect on the central link of the reflex arch.
