A Comparative Study of Cytoarchitectonics:Effects of Aging and Brain Weight Increase on Precentral Gyral and Insular Cortex of Human Brain
인대뇌(人大腦) 중심전회(中心前回)와 도중심전회(島中心前回) 각피질봉부간(各皮質峯部間)의 비교세포구축학(比較細胞構築學) 및 양피질(兩皮質)의 가령영향(加齡影響)에 관한 연구

- The cytoarchitectures of the Brodmann's cortical area 4 and 52 were compared
along with the effects of aging and weight increase on both areas. Samples were taken from
209 brains for area 4 and 153 brains for area 52. Cortical thickness, relative total neuronal
density (RTND), and relative total glial cell density (RTGD) were studied and statistically
significant differences between each age-or brain weight-group were examined. The following
results were obtained:
1. No difference between the cortical thickness of the two cortical areas was noticed in
regard to age, side and sex.
2. There was no significant difference between RTND of most of the age-or brain weightgroups
of the two areas of the same side brains.
3. Difference was shown between RTGD of 0-1 age group of area 4 and that of some age
groups of area 52 of the same side brains and also between those of some brain weightgroups
of the two cortical areas.
4. Mostly, sex or side didn't seem to cause different result in the above comparisons.
