Tables are formed with presence of interhemispheric asymmetry of more than 15 % of alpha-rhythm spectrum power. Graphs of interhemispheric and intrahemispheric asymmetry are plotted on detected periodically occurring sections of synchronization. Expression in % of intra- and interhemispheric asymmetry of synchronization processes is determined. Obtained variations of cortical synchronization asymmetry (by frequency, period and manifestation of asymmetry) enable to diagnose functional state and formed disorders in interaction of cortical and subcortical structures in a specific individual.
