Overview

The association fibers unite different parts of the same 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
