Abstract
This investigation is a study on the cytoarchitectonics
of the cerebral cortex in the gyrus top in the orbital
area of 121 Korean brains(68 brains of the male from
the newborn to the age of 85, 53 brair.s of the female
from the newborn to the age of (1).
The thickness of the total cortex ar.d ecch cortical
layer, the relative neuron density ar:d the relative glia
density inOOO",)3 of each cortical layer and the relative
total neuron and glia densities of the cortex were
observed, and the results were summerized as foils;
1. The mean thickness of the cortex in the 0-1
year group was 1. 73-1. 87111111, which was 80~82%
of the adult cortex thickness and increased rapidly to
2. 12~2. 18mm in the 2~5 year group which was
95~96% of the adult cortex and then it increased
slowly to the mean thickness of the adult cortex in
the 11~15year group and therafter it was relatively
stable but after 40 years of age it decreased slowly.
The mean thickness of the adult cortex was 2. 25mm.
The thickness of the cortex ir.creased rapidly as the
brain weight increased to l,100~1, 1999ms and thereafter
it increased very slowly as the brain weight
increased.
2. The highest neuron density in the 0-1 year
group decreased rapidly to the adult mean value in
the 2-5 year group and thereafter it was relatively
stable. The mean neuron density of the adult cortex
was 506~535.
The neuron density was highest in 300-499gms
stage of brain weight and it decreased gradually to
the adult mean valve in the 1, 100~1, 1999ms stage of
the brain weight and thereafter it was relatively stable.
3. The highest glia density was observed in the O~
1 year group but it was lower than the neuron density
in the same age group and it decreased very
rapidly to the minimum value in the 2~5 year group
and following this it gradually increased. The mean
glia density of the adult cortex was 593-615 and
this was higher than the mean neuron density of the
adult cortex.
In the 300~499gms stage of the brain weight the
mean glia density was highest and it decreased rapidly
to the minimum value in the 1, 100~1, 199 gms stage
and thereafter it increased gradually as the brain
weight increased.
4. The neuron density and glia density had no
sexual differer.ce and the left-right difference.
