인 대뇌 중측두회 (Brodmann 제21분야) 봉부피질의 세포구축학적 연구

Abstract

Cytoarchitectonics had been studied on summits of cortex of middle temporal gyrus for 149 normal Korean male and female, and age ranging from newborn till 85-year old. Then the cortical thickness and the cellularities of the summits of adult values were compared with those of the wall of the same cortex. The adult cortical thickness of the summits had bcen shown thicker than the wall's by 1. 22 and 1. 21 times on the left and right sides in male, respectively, and those of female's were I. 29 and I. 22 times thicker, respectively. The relative cellular densities of neuronal and glial in summit of adult had also been shown by lower rates. The rates of the male's 97.1% of the left and 92.7% on the right, and 93.8% and 96.4% in female, respectively. The glial's were also shown lower rates that in male 84.7% on left and 91.7% on right, and 89.3% and 92.4% in female had been calculated. On cytoarchitectural point of view thickening of same regional gyrus of normal has been filled with more dispersing neurofibrillar structure stained with other than for cell body. On view of such expectation the above facts could suggest us fibrilloarchitectural investigation for establishment of one of the other aspects of morphological bases on neurobiology.
