[The neuronal-glial correlations in areas of the frontal area of the brain in children at different stages of life].

Density of location of all the pyramid neurons (N), satellite glia (SG) and neurons surrounded by it (NS) in brain cortex fields 8 and 47 was studied by cytoarchitectonic and qualitative methods using MBI-3 microscope, Continuous growth of number of NS, SG and NS/N, the important parameters of neuronal activity, was established. This process is irregular. It lowers and intensifies at 2 "crucial" periods of ontogenesis, where difference in neuron activity between fields is most distinct. In puberty these difference are more manifested: the above mentioned parameters are sharply increased in field 8 and decrease in field 47.
