Regions of interest for tractography of the IFO. Tractography of the IFO was performed using a two-ROI approach, based on the connection between two regions of interest (ROI; arrows). The two ROIs were placed along the course of the IFO in the coronal plane of the DTI images at the level of the anterior commissure (Figure 1A) and pontine crossing fibers (Figure 1B), respectively. For measurements of regional differences in diffusion parameters, small ROIs were placed in the anterior, middle and posterior segments of the IFO (Figure 1C). The location and size of each ROI is shown in the sagittal plane. For comparison with the location of the IFO, see Figure 3.
