[Creation of steady alterations of motor activity in chick embryos under conditions of controlled experiments].
Steady alterations of motor activity in chick embryos were demonstrated under conditions of a controlled experiment, in production regimens of various directions. During controlled support by electrocutaneous stimulation of threshold amplitudes of the movements, the following characteristic time periods were distinguished: transitional, of steady alterations of motor activity with minimization of the amount of electrostimuli, and of the period of aftereffect. The conclusion is drawn about the united adaptive effect (minimization of biologically adverse influences) provided by the biorhythm of motor activity with directional potentiation of the activity of the components, which are not supported by adverse effects.
