Fig. 2.
Representative tracings from rats in which baroreflex regulation (BR) testing was performed after either sham lesion, 1 wk following T8 left hemisection, or 8 wk following a T8 left hemisection. Tracings show the baseline arterial pressure (AP), left renal sympathetic nerve activity (RSNA), and the BR response in RSNA. Changes in AP for BR were induced by intravenous infusion of sodium nitroprusside (SNP) and phenylephrine (PE). Dashed boxes indicate the corresponding AP and RSNA used for baroreflex quantification. Scale bar = 30 s.
