Abstract
This investigation is a study on the cytoarchitectonics
of the wall of the cerebral sulcus in the
transverse temporal gyrus (Brodmann’s area of 41)
of 142 Korean brains (82 of male. 60 of female)
from the newborns to the adults. The thickness of
the total cortex and each cortical layer. the relative
neuron density and the relative glia density in(1oo)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 85% of the adult and it increased
very rapidly during 2-5 years and it was 94% of the
adult. In the 16-20 year group it was maximum
thick and thereatfer it decreased gradually. The
mean thickness of the adult cortex was 2.13mm.
The mean thickness of the cortex increased rapidly
until the 700-899 g stage of the brain weight and
increased slowly until the 1.400• 1.499g stage of the
brain weight and thereafter it had a tendency of
slow decreasing as the brain weight increased.
2. The relative neuron density was highest in the
0-1 year group and it decreased vcry rapidly in the 2-5 year group and it decreased slowly until the 16
-20 year group'; and at this time it is eaqual as the
adult mean value. Thereafter it was relatively
stable. As the relation between the neuron u.cn:.,ity
and the brain weight, it was highest in 300•500g
stage of the brain weight and it decreased rapidly
until the brain weight wa~ 500-699g stage and it
decreased slowly until the brain weight was 1,100
1. 19B9 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
、,va s 594-604.
3. The relative 끽 lia density was high in the 0-1
year group and it decreased rapidly in the 2-5 year
group and was minimum value which was lower
than the adult mean value. and thereafter it incrc
ased gradually as the age increased. The mean
value of the relative gl iJ. d~nsity of the adult was
687-711 which is higher than that of the adult neuron
density (594-604). During the 300-499g stage of the
brain weight the relative glia density was high and
it decreased gradmlly to the minimum value (470530)
until the 700-899g 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
