  • Title: [Interhemispheric asymmetry of the spatial organization of human cortical potentials during the perception of emotional and indifferent images].

    Journal: Zh Vyssh Nerv Deiat Im I P Pavlova; 1989; 39(2):221-7. PubMed ID: 2750280.
    Abstract:
    In 13 healthy subjects dynamic characteristics of potentials spatial-temporal organization (PSTO) in the cortical left and right hemispheres at presentation of emotionally coloured and indifferent graphic images were studied by the method of quantitative evaluation of subsequent electroencephalotopograms. It is shown that, in contrast to the state of calm alertness, presentation of emotional and indifferent images leads to a decrease of the time of discordance in the hemispheres activity i.e. to synchronization increase. At the action of emotionally coloured images differences were found between the reorganizations of the left and right hemispheres, while there were no such differences at the presentation of indifferent images.
