尽管有证据表明小脑参与工作记忆 (WM)，但仍不清楚小脑支持 WM 中的哪些功能以及哪些结构参与 WM。我们测试了小脑是否参与传入信息的过滤或存储。通过对 29 名小脑缺血性中风患者进行统计脑图绘制方法，我们发现小脑起着看门人的作用，因为扁桃体、半月下叶和部分椎体的病变使得 WM 容易受到无关信息的影响。我们得出结论，小脑控制传入的 WM 信息。安·尼罗尔 2014；76:754-757
Although there is evidence that the cerebellum is involved in working memory (WM), it remains unclear which functions within WM the cerebellum supports and which structures are involved in WM. We tested whether the cerebellum is involved in the filtering of incoming information or in its storage. Using a statistical brain mapping approach in 29 patients with cerebellar ischemic stroke, we found that the cerebellum plays a gatekeeper role, as lesions of the tonsil, the lobus semilunaris inferior, and parts of the vermal pyramid rendered WM susceptible to irrelevant information. We conclude that the cerebellum controls incoming WM information. Ann Neurol 2014;76:754-757
