The influences of sequential baroafferent denervation on the stimulus–response curves between the average changes in mean arterial blood pressure (MAP) and HR (a) or RSNA (b) in response to phenylephrine and nitroprusside. The magnitude of the RSNA response in a given bout was expressed as a percentage against the baseline value, which was taken as 100 % in each condition. AoN–CSN; sequential denervation of the aortic nerves followed by denervation of the carotid sinus nerves.
