Off-line methods for detection and correction of EEG artefacts of various origin

Conventional methods for the correction of the effects of blinking and eyeball movement artefacts in the EEG have been considered. The limitations of present methods are reviewed. Considering the brain as a volume conductor, the ways of revealing the ocular movement artefacts in the frontal EEG leads have been suggested. On the basis of the proposed criteria an optimal method of artefact correction in the frontal EEG leads have been developed. General principles in the developing the program for the correction of artefacts of different origin are set forth.
