Abstract

A complex neuropsychological and electrophysiological analysis of the processing of visuospatial information was carried out in seven-to-eight-year-old mentally retarded children. A neuropsychological examination revealed the children with strong functional immaturity of left- and right-hemispheric structures. An analysis of the EEG parameters showed that specific features of intercentral integration during visuospatial performance in children with mental retardation depend on the type of hemispheric insufficiency. In right-hemispheric immaturity, ensembles of the regions of the left hemisphere become functionally significant, whereas in left-hemispheric immaturity, cortical areas, predominantly of the right hemisphere, become involved in interaction.
