The summary histograms of average power, coherence and GC before and after transition time for 10 rats in the KX group are shown here. The x-axis is the number of rats and y-axis is a value corresponding to the y-label. The symbol ‘’ in y-labels means cardiac, ‘’ respiratory and ‘’ brain, respectively. Symbols in parenthesis represent the frequency at which average was calculated. For example, means time average of was calculated along cardiac frequency (around 4 Hz). B here means the -frequency range. Blue bars represent time average before the transition (deep stage) and red bars represent time average after transition (shallow stage). Horizontal black lines are threshold calculated by permutation test. Numbers in histograms are the average of time averages across all the rats and its mean errors (deep stage upper and shallow stage lower). The mark * is put beside them if the distribution of time average is significantly different () between deep and shallow stages.
