[Effect of stimulation of alpha and beta presynaptic adrenoceptors on the liberation of noradrenaline produced by electric stimulation in rabbit carotid sinus].
The experiments carried out on the isolated carotid sinus in the rabbit demonstrated that alpha and beta adrenoceptors are capable of detecting the circulating catecholamines and the catecholamines of the synaptic cleft in order to modulate the release of noradrenaline from the sympathetic nerve endings in response to a potential action.
