Arcuate fibers

Arcuate fibers are a component of the human brain's white matter, specifically located in the cerebral cortex. They are also known as U-fibers due to their U-shaped trajectory.

Anatomy

Arcuate fibers are short association fibers that connect adjacent gyri within the same cerebral hemisphere. They are named for their curved or "arcuate" path. These fibers are found in the superficial layers of the cerebral cortex, just beneath the gray matter.

Function

The primary function of the arcuate fibers is to facilitate communication between neighboring regions of the cerebral cortex. This allows for the integration of information and the coordination of activities within the brain.

Clinical significance

Damage to the arcuate fibers can result in a variety of neurological disorders. For example, stroke or traumatic brain injury can disrupt the function of these fibers, leading to cognitive and motor deficits.
