[Study of the central and peripheral mechanisms in enhancement of arterial baroreflex in cats during noradrenaline infusion].

An increased suppression of electrical activity of the cardiac inferior nerve by the baroreflex during norepinephrine infusion can be eliminated by a preliminary infusion of monoamine. The data obtained corroborated our previous findings that an increase in arterial pressure due to norepinephrine infusion was essential for catecholamine increasing the baroreflex inhibition of electrical activity in sympathetic nerves.
