[Factors that determine the specificity of neural activity in early ontogeny].
Among the main factors determining the specificity of central nervous system functioning in the early ontogenesis, the principal role is assigned to the next ones: 1) Non-maturity of neural elements, their interconnections, regulatory and controlling mechanisms; 2) Heterochronism in structures and functions maturation; 3) Functional recapitulation; 4) The principle of structural and functional excessiveness; 5) Age-related inhibition of the ability of neural structures to periodic self-excitation and long-lasting self-maintaining reactions to afferent stimulation. The role of those factors is illustrated on examples of activity of non-mature nervous systems, proper to early neuro-ontogenesis of chick embryo and non-maturonate mammals, including man.
