Dissection of fiber tracts of the left hemisphere shown from the surgical angle. The cingulum bundle can be observed coursing around the genu of the corpus callosum anteriorly, with radiations to the superior frontal gyrus (A). Removal of the cingulum bundle (B) reveals the fibers of the corpus callosum, which connects cortices of both hemispheres. Tractography with GQI demonstrates the cingulum and its radiations (C).
