  • Title: [Electrophysiologic analysis of interhemispheric differences in mechanisms of visual recognition].

    Abstract:
    During tachistoscopic lateralized presentation of a series of geometrical figures in different conditions of recognition, early and late EP components were analyzed in the occipital, occipito-temporo-parietal, parietal and frontal cortical areas of the left and right cerebral hemispheres in juveniles and adult subjects. In both age groups, the right side dominance of the early EP component, P50-70, was revealed in the caudal cortical parts that may be connected with the predominant role of this hemisphere in the integral description of images. Asymmerty of the frontal associative zones gets formed at the mature age and consists in prevailing of the late EP components of the left frontal zone in comparison with the right one. The data are considered to reflect age-dependent mechanisms of classification type of recognition in the left hemisphere.
