title: Morphology of the human corpus callosum: the shape of its mediosagittal section.
abstract: The shape of the corpus callosum was studied on mediosagittal sections of 50 human brains. The terms "facies corticalis" and "facies profunda" are proposed for the sides of corpus callosum. Each of 50 brains had a different shape of callosal mediosagittal section and any available classification was not possible. In 94% of cases, the contour of callosal cortical surface exhibited a posterior depression and in 46% also an anterior one. Other details of callosal morphology influencing its shape on mediosagittal section (transverse folds, circumscribed depressions) were described. The junction of fornix and corpus callosum in 78% was in 3rd and in 14% in 4th quarter of callosal length. The possible significance of these findings for further studies of human brain morphology is discussed.
