Abstract: A method for calculating the betweenness centrality of EEG based on wavelet bicoherence is considered. It has been established that during cognitive load in some frequency bands, significant changes in the betweenness centrality occur that are not determined by the type of load.

Keywords: electroencephalogram, wavelet transform, synchronization, cognitive test.
