20 men of 21–22 took part in investigation. The electric activity of cortex in beta range and electric activity of both hands’ surface bending muscles are the indicators of informational processes under conditions of adequate testing (in condition of calm vigor, ideomotor functioning and rhythmic nonautomated right and left hand finger movements) was consider electric activity of cortex in altha- and ranges of beta. State of tuning to motions both right and counter-clockwise hands marked the considerable level of synchronization of work of particles of cortex, comparatively with the state of functional rest, especially in altha-ä³àïàçîí³ of EEG. Most correlation activity in both probed ranges of EEG was characterize frontal, central and parietal areas. In the process of implementation of motions in large parencephalons on a background the desynchronization of the probed frequency ranges of EEG plastic functional separation of cerebrum structures is formed.
