[Specifics of the formation of the alpha rhythm in different areas of the cerebral cortex in young children].
The age-specific features of distribution of capacity density values of modally specific monoherz components of optic alpha-rhythm and their response rearrangements to light stimulus suggest that in 2-3-year-old children, alpha-rhythm appears as three monoherz segments in the range 6-9 Hz with their heterodirectional changes. At this age stage of brain functional maturation, the authors have identified the border of synchronous and spasmodic changes in the spectral coherent indices of bioelectric activity formation in the projection and associative regions of the brain, which corresponds to 14-15 months of life.
