Abstract
This investigation is a study on the cytoarchitectonics
of the gyrus top in the angular gyrus (Brodmann'
s area of 39) of 152 Korean brains (86 brains
of male from the newborn to the age of 85. 66 brains
of the female, from the newborn to the age of 61).
The thickness of the total cortex and each cortical
layer, the relative neuron density and the glia density
in (lOOp)' 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 cortical thickness in the 0-1 year group
was 81. 6% of the adult cortical thickness and it increased
to the adult mean thickness in the 2-5 year
group. In the 6-10 year group it was the maximum
thickness and thereafter decreased gradually.
The mean cortical thickness of the adult was 2. 44
mm. The mean cortical thickness increased rapidly
until the 700 -899g stage of the brain weight and
thereafter it increased gradually.
2. The relative neuron density was highest in the
0-1 year group and decreased rapidly in the 2-5
year group which was about half number of that of
the 0-1 year group. Also it decreared gradually until
16-20 age group and thereafater it had a tendency
to increase in old ages. The mean neuron density of
the asult cortex was 485-517.
As the relationship between the relative neuron
density and the brain weight, it was highest in 300499gms
stage of the brain weght and decreased rapidly
in the 500~699gms stage and thereafter it deceased
- 21-
gradually.
3. The relative glia density was relatively high(515
~619) in the 0~1 year group and decreased to the
minimum value (359~415) in 2~5 year group and
thereafter increased gradually, which was highest(600
~635) in over 61 year age group. The mean value
of the glia density of the adult was 524~565. As the
relationship between the relative glia density and the
brain weight, it decreared gradully in 1. 100~1. 199
gms stage of brain weight and thereafter it increased
slowly.
4. The neuron density and glia density had no sexual
difference and left-right difference.
