Extreme Capsule is a Bottleneck for Ventral Pathway

As neuroscience literature suggests, the extreme capsule is considered a white matter tract. Nevertheless, it is not clear whether the extreme capsule itself is an association fiber pathway or only a bottleneck for other association fibers to pass. Via our review, investigating anatomical position, connectivity, and cognitive role of the extreme capsule, and by analyzing data from the dissection, it can be argued that extreme capsule is probably a bottleneck for the passage of uncinated fasciculus (UF) and inferior fronto occipital fasciculus (IFOF), and its different role of language processing is due to various tracts that pass it through.
