The present Cerebellar Classic highlights the experimental work of the Swedish neurophysiologist Olov Oscarsson (1931-1996) on the afferent innervation of the cerebellum by axons emanating from neurons in the spinal cord and the inferior olive. Historically, the schemes of cerebellar division had been principally based on the external morphology of lobules and fissures. However, the macroscopic anatomical division of the cerebellum does not coincide with its pattern of functional organization. By defining a system of longitudinal somatotopy, Oscarsson contributed to the much needed plan of cerebellar division that correlates experimental information on axonal connections with physiology. His contribution has ultimately led to the currently accepted microzonal modular scheme of cerebellar corticonuclear microcomplexes.
本小脑经典聚焦于瑞典神经生理学家 Olov Oscarsson（1931-1996 年）的实验工作，他研究了脊髓和下橄榄核神经元发出的轴突对小脑的传入神经支配。从历史上看，小脑的划分方案主要基于小叶和裂的外部形态。然而，小脑的宏观解剖划分与它的功能组织模式并不吻合。通过定义一个纵向体节系统，Oscarsson 为小脑的划分做出了急需的贡献，将轴突连接的实验信息与生理学联系起来。他的贡献最终导致了目前被广泛接受的小脑皮质核微复合体的微区模块方案。
