title: [The temporal correlations of the VEP of the visual and motor cortices during the perception and mental reproduction of an image in normal children and in those with intellectual disorders].
abstract: Temporal relations were analyzed between the VEP components in the occipital and central cortical areas in 7 and 10-year-old boys with normal intelligence, with mental retardation, and with debile oligophrenia in three experimental sessions with different instructions. It was found out that the intrahemispheric relations of the isopolar VEP components to a flash and patterned stimulus similar to those in adult persons developed in healthy children only to the age of 10 years. In children with intellectual deficiency such relations were distorted both in perception of the flash and patterned visual stimuli and during mental representation of the latter.
