The involvement of the cerebellum in suprasecond interval timing (i.e., timing in the seconds to minutes range) is controversial. A limited amount of evidence from humans, nonhuman primates, and rodents has shown that the lateral cerebellum, including the lateral cerebellar nucleus (LCN), may be necessary for successful suprasecond timing performance. However, many existing studies have pitfalls, such as limited timing outcome measures and confounded task demands. In addition, many existing studies relied on well-trained subjects. This approach may be a drawback, as the cerebellum is hypothesized to carry out ongoing error correction to limit timing variability. By using only experienced subjects, past timing studies may have missed a critical window of cerebellar involvement. In the experiments described here, we pharmacologically inactivated the rat LCN across three different peak interval timing tasks. We structured our tasks to address past confounds, collect timing variability measures, and characterize performance during target duration acquisition. Across these various tasks, we did not find strong support for cerebellar involvement in suprasecond interval timing. Our findings support the existing distinction of the cerebellum as a subsecond interval timing brain region. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

小脑对跨不同任务需求的超秒计时的贡献有限。

小脑参与超秒间隔计时（即秒到分钟范围内的计时）是有争议的。来自人类、非人类灵长类动物和啮齿动物的有限证据表明，小脑外侧，包括小脑外侧核 (LCN)，可能是成功的超秒计时性能所必需的。然而，许多现有研究存在缺陷，例如有限的时间结果测量和混淆的任务需求。此外，许多现有研究依赖于训练有素的受试者。这种方法可能是一个缺点，因为假设小脑进行持续的错误校正以限制时间可变性。通过仅使用有经验的受试者，过去的时间研究可能错过了小脑受累的关键窗口。在这里描述的实验中，我们在三个不同的峰值间隔时间任务中通过药理学方法使大鼠 LCN 失活。我们构建了我们的任务来解决过去的混淆，收集时间可变性措施，并描述目标持续时间获取期间的性能。在这些不同的任务中，我们没有找到对小脑参与超秒间隔计时的有力支持。我们的研究结果支持小脑作为亚秒级时间间隔脑区的现有区别。（PsycInfo 数据库记录 (c) 2022 APA，保留所有权利）。我们没有找到对小脑参与超秒间隔时间的有力支持。我们的研究结果支持小脑作为亚秒级时间间隔脑区的现有区别。（PsycInfo 数据库记录 (c) 2022 APA，保留所有权利）。我们没有找到对小脑参与超秒间隔时间的有力支持。我们的研究结果支持小脑作为亚秒级时间间隔脑区的现有区别。（PsycInfo 数据库记录 (c) 2022 APA，保留所有权利）。
