Abstract
This investigation is a study on the cytoarchitectonics
of the wall of the cerebral sulcus in the
parastriate area (Brodman's area of 18) of 179 Korean
brains (103 of male, 76 of female) from the newborns
to the adults. The thickness of the total cortex and
of each cortical layer, the relative neuron density
and the relative glia density in (1001')3 of each
cortical layer and the relative total neuron and
glia densities of the cortex were observed and the
results were summerized as follows:
1. The mean thickness of the cortex in the 0~1
year group was 76% of the adult cortex and it
increased very rapidly during 2~5 years and it was
thick as the adult cortex. In the 16~20 year group
it was maximum thick and thereafter it decreased
gradually. The mean thickness of the adult cortex
was 1. 83mm. The mean thickness of the cortex
increased rapidly until the 700~800gm stage of the
brain weight and increased slowly until the 1. 100~
1. 1999m stage of the brain weight and during this
stage it was thick as the adult cortex. Thereafter it had a tendency of slow increasing as the brain
weight increased.
2. The relative neuron density was highest in the
0-1 year group and it decreased very rapidly in the
2-5 year group and it decreased slowly until the 11
-15 year group and at this time it is equal as the
adult mean value. Thereafter it was relatively stable
but it had a tendency to increase in old age.
As the relation between the neuron density and the
brain weight, it was hightest in 300-500gm stage
of brain weight and it decreased rapidly until the
brain weight was 7oo-899gm stage and it decreased
slowly until the brain weight was 1. 100-1. 1999m
stage and in this stage it became eaqual as the adult
mean value. Thereafter it had a tendency to decrease
slowly as the brain weight increased. The mean value
of the neuron density of the adult cortex was 47350l.
3. The relative glia density was high in the 0-1
year group and it decreased rapidly in the 6-10 year
group and was minimun valve which was lower than
the adult mean value, and thereafter it increased
gradually as the age increased. The mean value of the
relative glia density of the adult was 606-654 which
was higher than that of the adult neuron density
(473-501). During the 3OO-500gm stage of the
brain weight the relative glia density was high and
it decreased gradually to the minimum value (542564)
until the 900-1. 1999m stage of the brain
weight and thereafter it increased gradually as the
brain weight increased.
4. The neuron density and glia density had no
sexual difference and left-right difference.
