Figure 3

Panel A depicts vertical Box and Whisker plots of normalized low frequency (LF) power, normalized high frequency (HF) power, and resultant LF/HF ratios for the right stellate ganglionectomy group (RSGX), sham (SHAM) operated control group, and the time control (CON) group. Each box contains a horizontal line indicating the median value of the treatment group, the lower and upper boundaries of each box represent the 25^th and 75^th percentile values, and the lower and upper whiskers (resembling error bars) depict the 5^th and 95^th percentiles. The asterisk in the top graph indicates that LF power of SHAM animals differed significantly from that of RSGX animals. Panel B shows LF power (top), HF power (middle), and LF/HF ratio (bottom) on each baseline day (BLD1–BLD4) for each treatment group. The vertical solid line extending from top graph to bottom graph points to the marked increase in LF/HF ratio on BLD3 for the SHAM group.
