Sex differences in inter- and intrahemispheric cerebral organization, found in previous studies, have been used to explain sex differences in cognitive abilities. This study highlights data to contradict such widely held beliefs. Intrahemispheric language organization was examined by determining the location of lesions causing aphasia by computed tomography. No sex differences in the incidence of anterior, posterior, or central lesions was found. The distribution of left-hemisphere lesions in stroke patients, with or without aphasia, was also equal among the sexes. This study does not support the postulated gender difference in intrahemispheric cerebral organization.
先前研究中发现的大脑半球间和半球内组织的性别差异,已被用于解释认知能力方面的性别差异。本研究强调了与这种广泛持有的观点相矛盾的数据。通过计算机断层扫描确定导致失语症的病变位置,以此来检查半球内语言组织情况。未发现前、后或中央病变发生率存在性别差异。有或没有失语症的中风患者中,左半球病变的分布在性别之间也相等。本研究不支持所假设的半球内大脑组织存在性别差异的观点。
