Failure to demonstrate sexual dimorphism of the corpus callosum in childhood.

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.
