[Classical and current aspects of the formation of motor dominance in man]

In the paper, significance of driving phenomenon for formation of motor dominant is considered and experimentally corroborated with the aid of autocorrelation and spectral analysis of the working man's EEG. The A.A. Ukhtomsky classical postulate has been complemented by contemporary ideas of the role of phasic relationships between the cortical activity for extablishing intercentral interconnections and the functional differentiation of working and irrelevant cortical structures. Data of correlation, crosscorrelation, and coherent EEG analysis enable to ascertain stages of formation of motor dominants at the cortical level and to judge of possible mechanisms of concentration of the dominant consstellations, as well as to show significance of the coadjustment for a common rhythm and of coincidence in phase of oscillations for improvement of the effectiveness of motor activity in man.
