摘　　要：近年来积累的资料表明,脊椎动物小脑不仅参与一向公认的躯体平衡、运动协调和技巧动作的获得,而且也同神经系统的高级认知功能(cognitive function)有关;但如何把这些功能活动同小脑特有、而又规则地遍布于小脑各部分的组件式结构(modular organization)联系起来,却存在较大的分歧和研究空间。本文仅就小脑的结构特点,以及如何将它们同近年来已成为研究热点的有关运动学习(motor learning)和经典式条件反射形成机制联系起来,作一些重点介绍。Evidence has been accumulating that the cerebellum in vertebrates contributes not only to the well-known postural balance, motor coordination, and the acquisition of skilled movements, but also to the higher cognitive function. However, there exist controversies about how the modular organization, being uniformly distributed throughout the cerebellum, fits with its roles in the motor learning and the classical conditioning, and these have long been hot spots in neuroscience research. Here, some basic advances in these respects were reviewed.
