Power spectral analyses of pulse interval (PI) and systolic arterial pressure (SAP) from Control + Sal, Control + LPS, SAD + Sal, and SAD + LPS groups. Representative tracings from each experimental group (panel A and B). Magnitude of low frequency (LF, panel C) and high frequency (HF, panel D) components of PI. Magnitude of HF component of LF component of PI (panel E). Results are presented as mean ± SEM. *p < 0.05, **p < 0.01, ***p < 0,001, and ****p < 0.0001 using the one-way ANOVA with Tukey’s post hoc test. Control + Sal (n = 8), Control + LPS (n = 8), SAD + Sal (n = 9), and SAD + LPS (n = 8).
