Presentation transcript:

Superior longitudinal fasciculus, sagittal view. Superior longitudinal fasciculus, sagittal view. This massive fiber bundle sweeps along the superior margin of the claustrum in a great arc. The term arcuate fasciculus is often used in reference to the superior longitudinal fasciculus or, specifically, its more arcuate portion.A, Gross dissection, lateral view.B, Directional map, parasagittal section. Note the color change from green to blue as the superior longitudinal fasciculus fibers turn from an anteroposterior orientation (white arrows) to a more superior-inferior orientation (arrowhead). The same phenomenon can also be seen in the uncinate fasciculus (yellow arrow).C, Tractogram. (See also Fig 7A.)‏ Brian J. Jellison et al.
