Fig. 2

a–c Group-averaged static characteristics of the total reflex arc, neural arc, and peripheral arc, respectively, of the carotid sinus baroreflex. CSP, carotid sinus pressure; AP, arterial pressure; SNA, sympathetic nerve activity. d The baroreflex equilibrium diagram constructed from the fitted neural and peripheral arcs. Downward and leftward arrowheads indicate the operating points of SNA and AP, respectively. e The relationship of normalized urine flow (nUF) versus SNA in the intact (INT) and renal denervation (RDN) sides. f The relationship of nUF versus AP in the INT and RDN sides. The vertical dashed line indicates the operating-point AP (op-AP). The horizontal arrowheads indicate nUF at op-AP. The P value was determined by the Wilcoxon signed-rank test. Data are expressed as mean ± SE values (n = 9 rats)
