摘要/Abstract

摘要： 本文应用图象分析电子计算机测量了51例中国人脑言语区的表面积並进行左右对比。1.左侧颞平台比右侧显著地大(P<0.01),右/左比率52.5%。2.额岛盖区的形态可分为6型,其表面积是左侧大于右侧,但无显著性差异。3.右侧顶下小叶较左侧略大。4.左半球的平均重量比右半球略重,两半球重量的相关系数为0.9878。本文还比较了两半球言语区的性别差及与日本人脑和西方人脑间的差别。

Abstract: 51 chinese brains were mearsured to examine the morphological asymmetry of the cortical speech areas with a videoplan computer.1. The temporal planum was significantly larger on the left than on the right side (P<0.01) .The ratio of R/L was 52.3%.2. The shapes of the frontal operculum were divided into 6 types. This area tended to be larger on the left than on the right side though the difference was not statistically significant.3. The area of the inferior parietal lobule tended to be larger on the right than on the left though the difference was not statistically significant.4. The mean weight of the left hemisphere was more heavy than that of the right side. The correlation coefficient was 0.9878.Comparisons were also made between the sexes and among the Chinese, Japanese and Westerner brains.
