A robust sex difference in the splenium of the corpus callosum, reflecting greater interhemispheric connectivity in women, was observed on magnetic resonance images from 114 individuals. In addition, bulbosity of the corpus callosum correlated with better cognitive performance in women but not in men, indicating that the degree of interhemispheric connectivity has different implications for men and women. These findings were based on a new image analysis technique which allows investigation of local variability in brain morphology.
在对114名个体的磁共振图像进行观察时，发现胼胝体压部存在明显的性别差异，这反映出女性半球间的连接性更强。此外，胼胝体的球度与女性更好的认知表现相关，而与男性无关，这表明半球间连接程度对男性和女性具有不同的影响。这些发现基于一种新的图像分析技术，该技术能够研究脑形态的局部变异性。
