The view of cerebellar functions has been extended from controlling sensorimotor processes to processing 'contextual' information and generating predictions for a diverse range of behaviors. These functions rely on the computation of the local cerebellar microcircuits and long-range connectivity that relays cerebellar output to various brain areas. In this review, we discuss recent work on two of the circuit elements, which are thought to be fundamental for a wide range of non-sensorimotor behaviors: The role for cerebellar granule cells in multimodal integration in the cerebellar cortex and the long-range connectivity between the deep cerebellar nuclei and the basal ganglia. Lastly, we discuss how studies on synapses and circuits of the cerebellum in rodent models of autism-spectrum disorders might contribute to our understanding of the pathophysiology of this class of neurodevelopmental disorders.
小脑功能的观点已经从控制感觉运动过程扩展到处理“上下文”信息,并为各种行为生成预测。这些功能依赖于局部小脑微电路的计算和长程连接,这些连接将小脑输出中继到各种大脑区域。在这篇综述中,我们讨论了最近关于两个电路元件的工作,这两个元件被认为是广泛的非感觉运动行为的基础:小脑颗粒细胞在小脑皮层中的多模态整合中的作用,以及深部小脑核与基底神经节之间的长程连接。最后,我们讨论了在自闭症谱系障碍的啮齿动物模型中研究小脑的突触和电路如何有助于我们理解这一类神经发育障碍的病理生理学。
