SOD1 Overexpression Preserves Baroreflex Control of Heart Rate with an Increase of Aortic Depressor Nerve Function

Figure 2

Baroreflex sensitivity. (a) The averaged regression lines for ΔHR/ΔMAP for the SNP-induced tachycardiac baroreflex for C57 () and SOD1 (). Regression lines for tachycardiac baroreflex response are similar between the two groups. (b) The averaged regression lines for ΔHR/ΔMAP for the PE-induced bradycardic baroreflex for C57 () and SOD1 (). Though visibly distinct, the slope of the regression line for SOD mice was not significantly different than that of C57 ().
