a Schema of experimental settings. Carotid sinus pressure (CSP) was controlled via a servo-pump system. Urine output was assessed from the hydrostatic pressure of cumulated urine. PC, personal computer. b An example time series obtained from one rat. CSP was changed in a stepwise manner with a step duration of 90 s. Sympathetic nerve activity (SNA) and arterial pressure (AP) decreased in response to the CSP elevations. Gray and black lines in the SNA plot indicate 10-Hz resampled and 2-s moving average signals, respectively. Gray and black lines in the AP plot indicate 200-Hz resampled and 2-s moving average signals, respectively. Urine volume (UV) is displayed as a 10-Hz resampled signal. The UV was greater on the renal denervation (RDN) side than the intact (INT) side. The open circles indicate 10-s averaged values used for data analysis
