[Sexual dimorphism of the corpus callosum?]

Morphometric studies carried out during the past years have led to the assumption that the splenium of the corpus callosum in the female brain is significantly larger in size and more bulbous than in the case of men. This result, obtained by the examination of a relatively small number of samples, was to be checked by investigations with a larger number of samples. Our own planimetric studies were based on a total of 70 dissection cases and 55 nucleal magnetic tomograms (NMR), both evenly distributed among men and woman. When applying the identical measuring parameters as those used by the above cited authors, a sexual dimorphism could not be confirmed. This result did also not change when additional modified measuring parameters were taken into consideration.
