A quantitative and morphological study was made of the corpus callosum in children to assess possible sex differences. The shape of the splenium of the corpus callosum was observed to vary between bulbous and cylindrical types with respect to the body of the callosum. The variation was not gender-specific and covariate analyses taking account of brain weight and age detected no differences in splenial width or area between males and females in childhood. This is in contrast to the situation reported in adults.
对儿童胼胝体进行了定量和形态学研究，以评估可能存在的性别差异。观察到胼胝体压部的形状相对于胼胝体主体在球根状和圆柱状类型之间有所不同。这种变化并非性别特异性的，考虑到脑重量和年龄的协变量分析未发现儿童期男性和女性在压部宽度或面积上存在差异。这与成人中报道的情况形成对比。
