[The method of correlation analysis of EEG synchronism and its possibilities]

A new method for estimation of EEG synchronism based on the analysis of correlation between amplitude modulation processes (envelopes) is considered. The efficiency of the given method is shown in different aspects: for detection of a topographical pattern, for analysis in frequency domains, for estimation of stability of the functional state and its changes, for detection of heterogeneous subgroups of subjects and outliers, for analysis of individual and group distinctions and distinctions in synchronism between symmetrical pairs of leads and hemispheric asymmetry, and for classifying division between mentally healthy subjects and deviations of schizophrenic spectrum with reliability approaching 100%.
