FIG 1. When viewed in multiple sections, the appearance of the association fibers on the principal eigenvector maps is consistent with known anatomy.
A, Sagittal 110 x 110-mm subimage close to the midline, passing through the cingulum (pink). Note that the fibers of the corpus callosum run at a slight angle through the plane (blue dots with short lines).
B, More lateral sagittal section obtained through the arcuate fasciculus (green), inferior longitudinal fasciculus (blue), and uncinate fasciculus (orange).
C, Coronal section obtained at the level of the posterior limb of the internal capsule. Fibers of the cingulum (pink), arcuate fasciculus (green), and uncinate fasciculus (orange) pass through the section (dots). Fibers of the posterior limb of the internal capsule (yellow lines) are running in-plane.
D, High-resolution 55 x 55-mm coronal subimage of the thalamic region. The strionigral and pallidonigral fibers are shown in light blue.
E, High-resolution axial surface coil image of the calcarine area at a 120 x 60-mm field of view. U-fibers connecting visual cortices are well seen.
