摘要
采用断面解剖学方法,对31例大脑的不对称研究表明,语言区结构左大于右;半球的不对称分布与CT报道吻合.后语言区的不对称性主要反映在枕叶长的不对称性上;用手习惯与半球不对称的关系极可能反映在枕叶宽和侧脑室后角长的不对称性上.虽然绝大部分人的前、后语言区均是左大于右。
By using the method of eross-sectional anatomy, we examined human eerebral asymmetries in 31 Chinese adult brain.The left cortical language areas is larger than the right. The distribution of the hemispheric asymmetries is compatible with that reported by CT scan.The asymmetry of the posterior language areas mainly reflect the asymmetry of the occipital length and the asymmetries of the wide occipital lobe and the wide occipital horn might be in relation to the handedness. Though both the anterior and the posterior language area are mostly larger on the left hemisphere,there is no relationship between them
