The stimulus–response curves of the average changes in systolic, mean, or diastolic AoNA (ΔAoNA) in responses to the respective blood pressure changes during spontaneous motor activity and pharmacologically evoked pressor interventions without (A) and with (B) the restraint HR at the lower intrinsic frequency. The stimulus–response curves of the average changes in systolic, mean, or diastolic CsNA (ΔCsNA) in response to the respective blood pressure changes during spontaneous motor activity and pharmacologically evoked pressor interventions without (C) and with (D) the restraint HR at the lower intrinsic frequency. Using the time course data over all bouts taken in Figs. 2 and 4, the average responses of the baroreceptor activities were plotted against the increases in SAP, MAP, and DAP to construct the stimulus–response curves of ΔAoNA or ΔCsNA during each pressor intervention with or without HR restraint
