Abstract

This work deals with elimination artifacts from electroencephalograms (EEGs). Though many methods for solving the problem have been proposed, they either require direct intervention of the researcher, are based on additional measurements (electrooculogram, electrocardiogram, etc.), or cannot remove artifact activity to a sufficient extent. We proposed an automated method that uses of the fact that the electromyogram (EMG) is not correlated and the artifacts of electrode movement at adjacent derivations and is based on the representation of electrical activity in one derivation through activity in other derivations. The analysis of the proposed method using model signals and examples of real EEG recordings has demonstrated its practical effectiveness.
