Authors studied on the development and cytoarchitectonics
of the cerebral cortex in the angular gyrus
(Brodmann’s area of 39) from 118 (62 males and 56
females) Korean fetal normal brains. and summerized
the results as follows:
1. The thickness of the cerbral cortex was 663μ
of male. 613μ of female at the fifth month of fetal
age and increased rapidly until the seventh month,
and up to the ninth month increased slowly and
thereafter increased rapidly again. As the relation
to the brain weight. up to 101~150gm stage of the
brain weight it increased rapidly. up to 400gm of
the brain weight increased slowly and thereafter it
increased rapidly again.
2. The differentation of the lamination of the
cerebral cortex began at the beginn of the sixth
fetal month (22nd week of the gestation period) and
was finished during the sixth fetal month.
3. The cell density of the cerebral cortex was very
high up to the seventh fetal month and thereatfer
it decreased gradually as the fetal age increased. As
the relation of the cell density with the brain weight.
up to 150gm of the brain weight the cell density was
very high and thereafter it decreased gradually as
the brain weight increased.
4. 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.
