The corpus callosum is the main commissure of the human brain. It is well known that cortical regions project to corresponding regions (homotopic projections) or to different regions (heterotopic) in the contralateral hemisphere. The precise topography of these fibres in the human brain, however, is largely unknown. The aim of the present study is to parcellate the midsagittal corpus callosum (MCC) on the basis of its connectivity. Therefore, we used diffusion probability tractographic tracking in order to analyse the connection distributions between the MCC and seven cortical regions, which are known to send projections through the corpus callosum.
