in conclusion , these results suggest the possible participation of the two types of alpha-adrenoceptors in the modulation of the sympathetic component of the baroreflex : alpha 1-adrenoceptor stimulation could inhibit , whereas alpha 2-adrenoceptor activation facilitates the reflex activity in the sympathetic fibres .
