Morphometric analysis of the human corpus callosum fails to reveal sex-related differences

No observations of sex differences in the splenium of the human corpus callosum are made. In the data there is no support for the concept that sex related functional hemispherical discrepancies are due to differences in area and width of the splenium of corpus callosum. However variability within a sex is often larger than the variability between the two sexes. The results are discussed with regard to a neurobiological theory of schizophrenia.
