가령 및 뇌중증가가 인대뇌 제1차 체감중추 및 제1차 운동 중추피질의 세포구축에 미치는 영향에 관한 비교연구

Abstract

The cortices between Brodmanns area 2 and 4 in homolateral hemisphere have been compared in terms 。f cytoarchitectonics with the effects of aging and weight gaining on 418 hemispheres from 209 normal human brains (115 of male and 94 of female) t.ken from newborn up to 85 years old in age range. 1. The thicker cortex in the area 4 was contrasted by statistically thinner of the area 2 without regard to the sides , sexes , and postnatal age or brain weight group was noted, especially, in that of juvenile than that of the senile 2. Scanty neuronal cellularity in the thicker cortex of the area 4 、v a s alao contrasted by the denser in that of the area 2, and was recognized at that of juvenile than that of senile and lighter the brain weight group than that of the heavy group regardless the sexes or the sides of brain. 3. The denser glial celluarity was shown in senile age and lighter the brain weight of the area 2 than those of juvenile and heavy weight fo the area 4. 4. In general, denser the cellultarity in thinner cortex of the area 2 noted than that of thicker cortex with the scanty in the area 4 of the adult value in present comparIson. 5. None of significant difference was noted between both the sexes in present observation
