Abstract
The corticies of summit of anterior transverse temporal gyrus (Brodmann's cortical
area 41) and of posterior transverse temporal gyrus (Brodrnann's cortical area 42) have
been compared in terms of aging effects on the cytoarchitecture of both areas. Samples were
taken from 290 hemispheres of 145 normal human brains (85 of male and 60 of female).
No statistically significant differences between the cortical thickness and the relative total glial
cell density of the two cortical areas were noted. But the relative total neuronal cell density of
Brodmann's cortical area 41 was significantly higher than that of area 42.
There was no aging effect on the relative total neuronal cell density in both cortical areas.
But the relative total glial cell density tended to increase gradually along with the increment of
age. The cortical thickness tended to increase gradually until the age 16-20 and thereafter decrease
in both cortical areas.
