Chemoreceptor discharges were recorded from the carotid sinus nerve of the cat in vivo, and their frequency was used as an index of receptor activity. The effects of dopamine on chemoreceptor activity were analyzed in normal and ischemic carotid bodies. Intra-arterial injections of dopamine (DA) induced various patterns of chemoreceptor responses; simple inhibition, inhibition followed by excitation, and simple excitation, depending upon doses and the time interval between two injections.
