인대뇌중심후회 후측구벽부 및 전측구벽부 피질간의 비교세포구축학 및 그 가령효과에 관한 연구

Abstract

The cortices of posterior wall (Brodmanns area 3) and anterior wall (Brodmann s area 2) at postcentral gyrus have been compared in terms of a comparative cytoarchitectonics and effects of aging on 368 hemispheres of 184 normal human brains (98 of male and 86 of female) taken from the age ranging newborn up to 85 years old. 1. The thicker cortex in the area 2 was contrasted by significantly thinner of the 3 in successive increase 。f the postnatal aging , except that of the youngest in both the areas , and somewhat senile cortical thining was noticed in both the areas , sides and sexes. 2. A consistency of the relative total neuronal cell density with statistical similarity regardless of the areas was affected by no means of the relation to the age, brain weight or the cortical thickness throughout the postnatal life-span , except in that of age-group of 0-1 year or 300-499gm of brain weight. 3. An insinuating increment of the relative total glial cell density was compared with concomitant increase of postnatal age or brain weight at both the areas , except that of the suckling young 4. The neuronal cellularity in both the areas after group of 2-5 years old was not discriminated statistically from that of the adult so far as the matter of the somesthetic cortex concern.
