[Transformation of cortical functional systems during the process of motor habit formation and disruption]

Specific cortical functional systems with synphasic and coherent activities were revealed in the left hemisphere as reflecting the motor program by means of the topical specifics. Diminishing of the activity synchronous character in the precentral and prefrontal areas and its increasing in the precentral and parietal inferior areas occurred in the course of motor automatization, i.e. during reduction of conscious control over movements and promotion of the intrinsic feed--back.
