Fig. 2: Anatomical scans of the patients.
From: No disconnection syndrome after near-complete callosotomy
Midsagittal T1-weighted MRI images with overlaid DTI-based fiber tractography are shown for each patient. Only select commissural fibers—the anterior commissure and corpus callosum –as well as some cerebellar and brainstem fibers, are displayed. Tractography parameters were adjusted for each patient to provide the clearest midsagittal depiction. The fiber orientations are color-coded: red for left-right, green for anterior-posterior, and blue for superior-inferior directions. All patients exhibit an intact anterior commissure (white arrow), but only patient BT* retains a preserved splenium (yellow arrow), in contrast to the complete sectioning of the corpus callosum in the remaining three patients.
