[Proliferation of piriform neurons in the rat cerebellar cortex in the pre- and postnatal periods of development].
The method of histoautoradiography with the use of H3-thymidine was applied to the study; there were established the periods of appearance in the cerebellar anlage of albino rats of neuroblasts differentiated into the piriform neurones of the cerebellar cortex; dynamics of the proliferative activity of these cellular elements in the course of the pre- and postnatal periods of development of the experimental animals was investigated. On the basis of the material obtained a conclusion was drawn that the last cell divisions (the result of cell differentiation were Purkinje's cells of the cerebellar cortex) stopped by the 13th--15th day of the embryonic development. No incorporation of the labeled precursor into the DNA of the nuclei of the differentiating piriform neurons occurred later.
