Abstract
Authors Studied on the development and cytoarchitec
tonics of the cerebral cortex in the Brodmann's area 1
in the post central gyrus of the 183(103 male, 80 female)
Korean fetal brains and summarized the results as follows:
1. The thickness of the cerebral cortex was very
thin of 161. 3f.l at the fourth month of fetal age and
increased very rapidly until the sixth month, relatively
rapidly until the seventh month, very slowly until the
ninth month and thereafter very rapidly. As the relation
to the brain weight, up to 150 gm of brain weight, it
increased very rapidly, up to 400 gm of brain weight
increased very slowly and thereafter it increased very
rapidly again.
2. The differentiation of the lamination of the cerebral
cortex began at the end of the sixth fetal month (23 rd
week of the gestation period) and during the seventh
fetal month the lamination of the cortex had almost
occurred but even at the end of the seventh month there
was some undifferentiated cortex and so there might be
a great individual difference of lamination.
3. The cell density of the cerebral cortex was very
high during fifth, sixth and seventh fetal months and
thereafter it decreased gradually as the fetal age increased.
As the relation of the cell density with the brain
weight, up to 150 gm of brain weight the cell density
was very high and thereafter it decreased gradually as
the brain weight increased.
The nerve cells of the fetal cortex might be increased
very rapidly up to the seventh month of fetal age and
thereafter the number of the nerve cells of the cortex
might be stabilized.
