Abstract
The dynamics of electrical activity of the brain in various physiological states are traditionally studied by analyzing dominant rhythms separately. However, in recent years the concept of cross-communication of different cortical rhythms has also been discussed. Using this concept, we study the effects of 1-day sleep deprivation on the coordination of rhythm pairs and compare two methods for assessing their cross-correlations: the Pearson correlation coefficient (PCC) and detrended cross-correlation analysis (DCCA) with its extended version. We show that the latter approach may reveal differences in electrocorticogram (ECoG) signals for a larger number of pairs.
