What is the function of arcuate fibers in the brain?

Arcuate fibers are a type of white matter tract in the brain that connect different regions of the cerebral cortex within the same hemisphere. Their primary function is to facilitate communication and integration of information between adjacent cortical areas, particularly in the frontal, temporal, and parietal lobes. This connectivity plays a crucial role in various cognitive processes, including language, memory, and sensory perception.
