Association fibers comprise local, neighborhood and long association fibers. Local, or U-fibers, are closely apposed to the undersurface of the sixth layer, and are directed to cortical regions in the same or adjacent gyri. Neighborhood association fibers are distinct from local U-fibers and are directed to nearby cortical regions, e.g., the fibers that connect the inferior parietal lobule to the medial parietal cortex. Long association fibers are the named fiber tracts that travel within the central part of the white matter of the core of the gyrus and link distant cortical areas within the same hemisphere | Association fibers comprise local, neighborhood and long association fibers.
