Paraventricular and supraoptic nuclei of the hypothalamus mediate cardiovascular responses evoked by the microinjection of noradrenaline into the medial amygdaloid nucleus of the rat brain

► Injection of NA into the MeA of rats caused pressor and bradycardiac responses. ► CoCl2 in the PVN reduced pressor and bradycardic responses to NA in the MeA. ► CoCl2 in the SON reduced pressor and bradycardic responses to NA in the MeA.
