Abstract
This investigation is a study on the cytoarchitec一
tonics of the wall of the cerebral sulcus in the angular
gyrus (Brodmann ’ s arca of 39) of 152 Korean brains
(86 of male, 66 of fcmale) 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 C100U) 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 81% of the adult and it increased very
rapidly during 2-5 years and it was thick as the adult
cortex. In the 6-10 year groups it was maximum thick
and thereafter it decreased gradually. The mean thickness
of the cortex increased rapidly until the 700-800g
stage of the brain weight and increased slowly until
the 1. 1애- 1. 1999 stage of the brain weight and during
this stage it was thick as the adult cortex. Thereafter
it had a tenducy 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 groups and at this time it is eaqual 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 highest in 300 많)()g stage of brain
weight and it decreased rapidly until the brain weig
ht was 500-700g stage and it drecreased slowly until
the brain weight was 1. 1000-1.200g stage and in this
stage it became eaqual as the adult mean value. Thereafter
it had a tendevcy to decrea~e slowly as the
brain weight increased. The mean value of the neuron
density of the adult was 499-559.
3. The relative glia 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 increased gradually
as the age increased.
The mean value of the relative glia density of the
adult was 558-641 which is higher than that of the
ad비t neuron density(4~뽕559). During the 300-500g
stage of the brain weight the relative glia density was
high and it decreased gradually to the minimum value (465-521) until the 1. 100- 1. 200g stage of the brain
weight and thereafter it increased gradully as the brain
weight increased.
4. The neuron density and glia density had no
sexual defference and left-right ‘lifference.
