Correlations between the Signal Complexity of Cerebral and Cardiac Electrical Activity: A Multiscale Entropy Analysis
Figure 4
Inverse association between the multiscale entropy (MSE) values of the awake RRI and fast-PS EEG.
(a) Regions with significant inverse correlation between the summed MSE values on the scales 11−20 of the awake RRI and the summed MSE values on the scales 6−20 of the photic-simulated EEG at frequency 12, 15, 18 and 24 Hz (fast-PS, duration 10 seconds and interval 10 seconds) after Bonferroni corrections (corrected p-values = original p-values19, alpha = 0.05). r and p denote the Pearson’s partial correlation coefficient and corrected significance level, respectively. (b) The brain map illustrates regions with significant association. The relative brightness is according to the sequential p-values from the smallest one (O1, O2 and C4).
