METHOD OF REMOVAL OF EYE-MOTION ARTEFACTS ON ELECTROENCEPHALOGRAMS Russian patent published in 2015 - IPC A61B5/476 

FIELD: biotechnology.

SUBSTANCE: signals of electroencephalograms and electrooculograms are registered. The signals of electrooculograms are normalised, which characterise the vertical and horizontal eye movements, in the range of [1.5, 5] s. The procedure of subtraction from the initial signal of electroencephalogram of the scalar product of the initial signal of electroencephalogram and the normalised reference signal of electrooculogram is carried out, which characterise the vertical eye movements. Also subtraction from the received signal of the scalar product of this signal and the normalised reference signal of electrooculogram is carried out, which characterise the horizontal eye movements. As a result, the signal is obtained, purified from the oculomotor artefacts.

EFFECT: method enables to simplify the procedure of removal of oculomotor artefacts while maintaining high reliability of the obtained record of electroencephalogram, which is achieved by using the method of Gram-Schmidt orthogonalisation.
