Abstract
Authors studied on the development and cytoarchitectonics
of the cerebral cortex in the orbital area of
the frontal lobe (Brodmann's area of 11) from 118
(63 males and 55 females) Korean fetal normal brains,
and summarized the results as follows:
1. The thickness of the cerebral cortex was 547/-1
of male, 500/-1 of female at the fifth month of fetal
age and increased rapidly until the sixth month, and
from the seventh month to the ninth month increased
slowly and thereafter increased rapidly. As the relation
to the brain weight, up to 51~ lOOgm 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 differentiation of the Iarnintation of the cerebral cortex began at the beginn of the seventh
fetal month (26th week of the gestation period) and
during the seventh fetal month the laminaion 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 and sixth 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 lOOgm 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 sixth month of fetal
age and thereafter the number of the nerve cells of
the cortex might be stabilized.
