我们研究了额枕束（FOF）和大脑白色物质中相关束的历史，因为它们与连接神经解剖学、磁共振纤维束成像和临床神经学的当代相关性。术语“FOF”起源于Forel和Onufrowicz，他们错误地识别了胼胝体发育不全患者的异常纵向胼胝体纤维。这个错误很快就被认识到，Dejerine描述了一个连接额叶和枕叶的实际FOF，但是大体解剖和病变变性方法无法将FOF与Muratoff的胼胝体下束和邻近的白色物质束区分开来。随后对可能不存在的“下FOF”的描述导致FOF被错误地命名为事后“上级FOF”，并且早期文献中的其他不精确的解剖学概念和术语仍然存在。我们使用同位素顺行束示踪剂对脑纤维通路进行的分析（Schmahmann & Pandya，2006）解决了早期的不确定性，并提供了关于这些纤维通路功能的假设。
We investigated the history of the fronto-occipital fasciculus (FOF) and related tracts in the cerebral white matter because of their contemporary relevance for connectional neuroanatomy, magnetic resonance tractography, and clinical neurology. The term "FOF" originated with Forel and Onufrowicz who misidentified aberrant longitudinally oriented callosal fibers in patients with callosal agenesis. This error was soon recognized, and Dejerine described an actual FOF linking frontal and occipital lobes, but gross dissection and lesion-degeneration methods could not distinguish the FOF from the subcallosal fasciculus of Muratoff and neighboring white matter bundles. Subsequent descriptions of a probably nonexistent "inferior FOF" have led to the FOF being misnamed post-hoc "superior FOF," and other imprecise anatomical concepts and terminologies from the early literature are still perpetuated. Our analysis of brain fiber pathways using isotope anterograde tract tracers (Schmahmann & Pandya, 2006) resolves the earlier uncertainties and provides hypotheses regarding functions of these fiber pathways.
