Modern Problems of Brain-Signal Analysis and Approaches to Their Solution

Abstract

A number of problems of modern quantitative EEG are considered: the non-stationarity of the processed signal, the decreasing accuracy of the received results due to the averaging effect in the spectral analysis methods used in computer EEG, and the impossibility of detecting complexes in analyzed EEG without involving a clinician. A structural (syntactic) approach is suggested, which reduces the negative effect of these problems, and the mathematical apparatus for its realization is developed. The results of application of the structural approach to analysis of a real EEG are given.
