Association Fiber Information
Functionally, bundles of axons within the brain, called fibers, can be categorized into association fibers, projection fibers, and commissural fibers.
The association fibers unite different parts of the same cerebral hemisphere, and are of two kinds: (1) those connecting adjacent gyri, short association fibers; (2) those passing between more distant parts, long association fibers.

Short association fibers
The short association fibers lie immediately beneath the gray substance of the cortex of the hemispheres, and connect together adjacent gyri.
Long association fibers
The long association fibers include the following:
| Name | From | To |
| uncinate fasciculus | frontal lobe | temporal lobe |
| cingulum | cingulate gyrus | entorhinal cortex |
| superior longitudinal fasciculus | frontal lobe | occipital lobe |
| inferior longitudinal fasciculus | occipital lobe | temporal lobe |
| perpendicular fasciculus | inferior parietal lobule | fusiform gyrus |
| occipitofrontal fasciculus | occipital lobe | frontal lobe |
| fornix | hippocampus | mammillary bodies |
| Arcuate fasciculus | frontal lobe | temporal lobe |
Diffusion tensor imaging is a non-invasive method to study the course of association fibers.
