For detailed description see text.

^*Discontinuity of streamlines in the left hemisphere at the transition of the PLIC into the corona radiata.

^**In subject 6 histology was only available for the right hemisphere.

^***Absence of normal mediolaterally oriented corpus callosum projections, successful tractography of longitudinally cut fibers, and reduced number of streamlines in regions of the Probst bundle with predominantly perpendicularly cut axons.
