Abstract

Using high-resolution in vivo magnetic resonance morphometry we measured the midsagittal area of the corpus callosum and total forebrain volume in 120 healthy young adults (mean age (+/- s.d.) 25.7 +/- 4.7 years). The forebrain volume-adjusted size of the corpus callosum was larger in women than in men (32 mm2 mean difference; p = 0.011). Handedness had no effect in this measurement. The morphometric data confirm a gender difference in cerebral structural organization.

摘要

我们使用高分辨率活体磁共振形态测量法，对120名健康年轻成年人（平均年龄（±标准差）25.7±4.7岁）的胼胝体中矢状面面积和前脑总体积进行了测量。经前脑体积校正后，女性的胼胝体大小大于男性（平均差异为32平方毫米；p = 0.011）。利手在该测量中没有影响。形态测量数据证实了大脑结构组织存在性别差异。
