Definition

Arcuate fasciculus: The arcuate fasciculus is a bundle of fibers that serves as the neural pathway connecting the expressive (i.e., Broca’s area) and receptive (i.e., Wernicke’s area) language areas to one another and plays a vital role in repetition [3].

Description

The arcuate fasciculus is a neural pathway compiled of fiber bundles that extend anteriorly from the posterior portion of the temporal lobe to the posterior region of the inferior prefrontal lobe, thereby linking the expressive (i.e., Broca’s area) and receptive (i.e., Wernicke’s area) language centers of the cortex [2, 3]. In terms of neurocognitive functioning, the arcuate fasciculus is said to play a vital role in repetition [1]. Specifically, as auditory information comes into the neural system that is to be repeated, it is first processed by the receptive center of the brain (i.e., Wernicke’s). Upon recognizing the nature of the information to be repeated, the neuronal...
