title: [Interhemispheric asymmetry of visual evoked potentials in psychopathies].
abstract: The paper deals with a study of intrahemispheric visual evoked potentials (EP) in normals (10 individuals) and in psychopathic personalities (40 cases). EP were registered in the occipital and central areas of the right and left hemisphere to indiffirent and significant flashes. In normals an intrahemispheric asymmetry of visual EP was detected: the wave amplitude (P3) with a peak latency 160--170 ms in the left occipatal area was larger than the amplitude of the same wave in the right occipital area. An adjoinment of signal significancy to stimulations in normals increased to a large degree the intrahemispheric asymmetry of EP in the left hemisphere. In psychopathy even indifferent and signal-significant stimulations of EP, registered in the occipital area are bilaterally symmetrical.
