Studying of human’s mental state during visual information processing with combined EEG and fNIRS

Abstract

We provided a combined analysis of electroencephalogram and functional near-infrared spectroscopy signals in order to investigate the process of prolonged visual perception. We investigated perception and decision-making processing during long-term and intense cognitive load. We found characteristic changes in electrical and hemodynamic activities during the neurophysiological experiment. The relationship was found between the EEG characteristics and the ΔO2Hb oscillation registered with the help of functional near-infrared spectroscopy.
