  • Title: [Interhemispheric asymmetry of the spatial-temporal organization of human cortical potentials during the performance of an intellectual task].
    Author: Iakovenko IA.
    Journal: Zh Vyssh Nerv Deiat Im I P Pavlova; 1989; 39(4):595-602. PubMed ID: 2816042.
    Abstract:
    In 15 healthy subjects, during accomplishment of an intellectual task spatial-temporal organization of potentials (PSTO) of the left and right cerebral hemispheres was studied by the method of quantitative evaluation of successive topograms (momentary values of potentials under leading electrodes). It was found that the time of absence of resemblance (TAR) in the cortical PSTO during intellectual activity occupied totally 10-30% of the recording time what is considerably less than in the state of calm alertness where this time varied within 4-57%. Productivity of task accomplishment apparently is connected to a greater extent with TAR than with the character of intrahemispheric reconstructions of the PSTO.
