Inhibition by CST sectioning on the increases in the MBF evoked by activation of the sympathoadrenal system during high spontaneous activity in the CST. The mean ± standard error of the mean (SEM) of the changes (black bars) in the MBF on both sides, left LBF (top), and VC of each measuring site (bottom) evoked by electrical stimulation of the left AN (20 s, 10 V, 20 Hz, 2-ms pulses) alone (AN stim.), left CST sectioning (CSTs), and AN stimulation in combination with CST sectioning (CSTs + AN stim.) or propranolol (1 mg/ml; (AN stim. + Pro) (n = 10 in each group) are shown. Statistical significance of the differences from base value before AN stimulation was determined by analysis of variance (ANOVA) followed by a post hoc test [Fisher’s protected least significant difference (PLSD) test]. *P < 0.001 vs. base value. A significant difference between data sets (P < 0.05, P < 0.001) or non-significant difference (NS) is indicated above the appropriate square bracket (ANOVA followed by a contrast test)
