Abstract: Results of multiscale correlational analysis in application to EEG cortical rhythms detection improvements are presented and in detail discussed. In particular, the importance of frequency−temporal cone−shaped representations calculation techniques (which is the particular case of the correlation distributions) based on therecently introduced concept of the analytical spectra is in the center of discussion. Unlike classical spectral analysis, aimed at high resolution assessment of individual frequencies, the proposed methods are focused primarily on detection and monitoring of oscillatory neurons activity in the wide main frequency ranges.

Key words: DSP, time−frequency EEG analysis, multiscale correlational analysis, analytic spectra.
