Grouped data showing the effect of T3 left hemisection (or sham lesion, n = 10) after either 1 wk (n = 10) or 8 wk (n = 9) on baroreflex relationship on left RSNA (A), maximal gain of the baroreflex response (B), maximum plateau of RSNA during baroreflex testing (C), and minimum plateau of RSNA during baroreflex testing (D). The RSNA responses were measured as %Δ from the respective baseline RSNA before baroreflex testing. Values are means ± SE. Significantly different from *control, and #both control and 8 wk: P < 0.05.
