在许多神经科学领域，局部和全局节律性的研究越来越受到重视。这些网络影响可以直接影响神经元群如何相互作用，为不同的环境组织。小脑皮层蕴藏着多种这样的局部电路节奏，这些节奏来自小脑皮层本身的节奏，或者来自重要事件的节奏。我们在这里提出了在啮齿动物和灵长类动物中记录的某些小脑振荡现象。这些发生在不同的频率范围内：从已知的4-25 Hz波段的振荡，如橄榄小脑振荡活动和颗粒细胞层振荡，到最近报道的浦肯野细胞层的缓慢（<1 Hz振荡）和快速（bb0 - 150 Hz）活动。许多这些振荡自发地出现在电路中，并由行为指令调制。我们在这里回顾了这些振荡是如何被记录下来的，它们的一些调节机制，并确定了一些它们可以相互作用的小脑节点。特别强调的是如何通过运动和某些神经病理表现来调节这些振荡。许多这些振荡可能对小脑处理信息的方式以及它在各种情况下如何与其他结构相互作用产生明确的影响。
In many neuroscience fields, the study of local and global rhythmicity has been receiving increasing attention. These network influences could directly impact on how neuronal groups interact together, organizing for different contexts. The cerebellar cortex harbors a variety of such local circuit rhythms, from the rhythms in the cerebellar cortex per se, or those dictated from important afferents. We present here certain cerebellar oscillatory phenomena that have been recorded in rodents and primates. Those take place in a range of frequencies: from the more known oscillations in the 4–25 Hz band, such as the olivocerebellar oscillatory activity and the granule cell layer oscillations, to the more recently reported slow (<1 Hz oscillations), and the fast (>150 Hz) activity in the Purkinje cell layer. Many of these oscillations appear spontaneously in the circuits, and are modulated by behavioral imperatives. We review here how those oscillations are recorded, some of their modulatory mechanisms, and also identify some of the cerebellar nodes where they could interact. A particular emphasis has been placed on how these oscillations could be modulated by movement and certain neuropathological manifestations. Many of those oscillations could have a definite impact on the way information is processed in the cerebellum and how it interacts with other structures in a variety of contexts.
