Association fibers are axons that connect cortical areas within the same cerebral hemisphere.[1]
In human neuroanatomy, axons (nerve fibers) within the brain, can be categorized on the basis of their course and connections as association fibers, projection fibers, and commissural fibers.[1]
The association fibers unite different parts of the same cerebral hemisphere, and are of two kinds: (1) short association fibers that connect adjacent gyri; (2) long association fibers that make connections between more distant parts.
Short association fibers
Many of the short association fibers (also called arcuate or "U"-fibers) lie immediately beneath the gray substance of the cortex of the hemispheres, and connect together adjacent gyri.[2] Some pass from one wall of the sulcus to the other.[2]
Long association fibers
The long association fibers connect the more widely separated gyri and are grouped into bundles.[2] They include the following:
Diffusion tensor imaging is a non-invasive method to study the course of association fibers.
