研究了40例入院的右撇子（男20例，女20例）死后大脑皮层未受损伤的胼胝体不同区域的大小与左脑区解剖不对称的关系。在胼胝体的解剖不对称性和区域大小方面，性别差异均无统计学意义。男性颞平面裂隙不对称的绝对值与峡部大小呈负相关，而女性无相关。此外，在男性中，颞平面的大小与胼胝体中部的大小之间存在显著的负相关，而在女性中则没有。颞平面\左右\的不对称性与平面的总大小（左+右）之间没有相关性。这些发现限制了有关胼胝体连通性变化导致半球特化的个体发生理论和关于半球间组织的性别差异的理论。
The relationship between anatomical asymmetries in the perisylvian region and the sizes of different regions of the corpus callosum was investigated post-mortem in 40 brains of right-handed hospital admissions (20 males, 20 females) with no cortical involvement. There were no sex differences either in anatomical asymmetries or in regional size of the callosum. There was a negative correlation between the absolute value of Sylvian fissure (planum temporale) asymmetries and the size of the isthmus in males but not in females. Further, there was a significant negative correlation between the size of the Sylvian fissure (or planum temporale) and the size of the callosal mid-body in males but not in females. There was no correlation between the asymmetry of the planum temporale \left-right\ and total size of the planum (left + right). These findings constrain theories about the ontogenesis of hemispheric specialization through changes in callosal connectivity and about sex differences in interhemispheric organization.
