The principal errors of spectral and coherent analysis are discussed, and the mathematics of these methods
is not related to EEG nature. In this regard, in 2011, the new method was developed for evaluating EEG
synchrony by the correlation of envelopes, which has a direct and fundamental physiological meaning.
The basics of this method and the methodology of subsequent multilateral statistical analysis are
considered. The effective use of the method for identifying individual and intergroup differences in the
norm and several types of schizophrenia, depressive diseases, five stages of sleep, and similar functional
states are presented.
