title: [Stable motor states in embryogenesis and their physiological analysis].
abstract: The experimental data obtained showed the reasonableness of N. P. Bechtereva's concepts in elucidation of regularities of ontogenesis of the nervous activity. The possibility of formation of new stable motor states was shown for the terminal period of embryogenesis (starting from the 18th day), the states being actualized by a forming long-term memory matrix. Rigid and versatile ("flexible") links were revealed in coordinated rearrangements of the biorhythmological structure of movements on the basis of the principle of minimization of maintaining cerebral area in the process of formation of new stable motor states.
