Arcuate fasciculus
neural pathway connecting Broca's area and Wernicke's area
In neuroanatomy, the arcuate fasciculus (AF; from Latin 'curved bundle') is a bundle of axons that generally connects Broca's area and Wernicke's area in the brain. It is an association fiber tract connecting caudal temporal lobe and inferior frontal lobe.
Structure
The arcuate fasciculus is a white matter tract that runs parallel to the superior longitudinal fasciculus. Due to their proximity, they are sometimes referred to interchangeably. They can be distinguished by the location and function of their endpoints in the frontal cortex. The arcuate fasciculus terminates in Broca's area (specifically BA 44) which is linked to processing complex syntax. However, the superior longitudinal fasciculus ends in the premotor cortex which is implicated in acoustic-motor mapping.
Connection
Historically, the arcuate fasciculus has been understood to connect two important areas for language use: Broca's area in the inferior frontal gyrus and Wernicke's area in the posterior superior temporal gyrus. It is mostly considered to be an oversimplification, but this model is still utilized because a satisfactory replacement has not been developed. The topographical relationships between independent measures of white matter and gray matter integrity suggest that rich developmental or environmental interactions influence brain structure and function.
“Arcuate fasciculus” enters the record as neural pathway connecting Broca's area and Wernicke's area. Crown Archives preserves that source wording while asking what Arcuate, fasciculus and neural can confirm, complicate or overturn.
Why this record matters
“Arcuate fasciculus” is worth following because a concise public description often conceals a longer documentary argument. Here, Arcuate, fasciculus and neural provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 11, 2026. The linked authority identifier is Q615697. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
