[Ontogenesis of the entorhinal region of the human cerebral cortex]

The ontogenesis of the entorhinal region of the human brain was studied on a series of continuous frontal sections of the brain in 13 pre- and postnatal ages. The sections were stained with crezyl violet. Use was made of the quantitative methods. The study revealed some peculiarities in the ontogenetic development of certain subregions and areas of the entorhinal cortex of the human brain. Peculiar of the development of the human antorhinal region in the second half of pregnancy is appearance of new areas typical in their structure of the man brain only. The entorhinal region cortex was found to develop intensely in the postnatal ontogenesis; its basic cytoarchitectonic development is completed by the 2nd--4th year of the life.
