As neuroscience literature suggests, extreme capsule is considered a whiter matter tract. Nevertheless, it is not clear whether 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 bundles in 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 these fasciculi are responsible for the respective roles in language processing.
正如神经科学文献所表明的，极端囊被认为是一条白质束。然而，极端囊本身是一条联合纤维通路还是仅仅是其他联合纤维通过的一个瓶颈尚不清楚。通过我们的综述，研究极端囊内纤维束的解剖位置、连接性和认知作用，并分析解剖数据，可以认为极端囊可能是钩束（UF）和额枕下束（IFOF）通过的一个瓶颈，并且这些纤维束在语言处理中各自发挥作用。
