A New Electroencephalography Marker of Cognitive Task Performance

Abstract

A universal biomarker is proposed that is based on calculating the dispersion of the ratio of alpha- and beta-rhythm energies in registered electroencephalography signals and reflecting the level of the components of the cognitive resource of a learner. The Bourdon proofreading test is used as an example to show this biomarker correlates strongly with the main indicators of success in performing standardized cognitive tasks.
