Electrophysiological analysis of the perceptive activity of children with normal and delayed mental development


, : Electrophysiological analysis of the perceptive activity of children with normal and delayed mental development. Zhurnal Vysshei Nervnoi Deyatel'nosti Imeni I P Pavlova 36(1): 20-27

Visual EPs of the occipital, parieto-temporal-occipital, parietal and central areas of the left and right hemispheres in response to unilaterally presented stimuli (figures) were analyzed in normal and developmentally backward children. In tasks of detection and recognition of the signal, developmentally backward children manifested a lowered reactivity of associative cerebral structures, especially of the left hemisphere, during perceptive activity, and a changed, in comparison with normal, interhemispheric interaction in processing of sensory information. It is suggested that properties of brain system organization during perceptive activity reflect to a certain extent neurophysiological mechanisms of disturbance of cognitive processes in developmentally backward children.
