Figure 7:
Heart rate variability was lower in MSEW mice (n=16) compared to NR mice (n=12) throughout the CSS protocol (left panels). Total (7A), LF (7B) and HF (7C) power were lower in the MSEW mice during the CSS protocol (left panels) as were the sums of total, LF, and HF for the 4-hour stress period (middle panels). Change from baseline (right panels) was similar for total, LF, and HF. LF/HF ratio (7D) was similar between both groups. Statistical analysis was performed by repeated measures 2-way ANOVA.
