CEREBELLAR NUCLEI IN EYE MOVEMENT CONTROL & ADAPTATION

这项研究的目的是了解小脑是如何 眼球运动。我们知道，小脑在每一个 我们所做的运动，但我们不知道它到底做了什么或它是如何做的 做到了。我们可以通过研究小脑来更快地取得进展 眼球运动比肢体运动或其他运动更重要，因为我们知道 更多的是关于大脑如何产生眼球运动的 动静。我们的研究结果也将帮助我们理解大脑是如何 产生眼球运动。眼球运动是我们眼球运动的重要组成部分 活着。每天我们都会做数以万计的眼球运动来观察 在感兴趣的事情上，并看清楚它们。眼部异常 运动严重降低了我们阅读、观看和视觉指导的能力 我们的其他动作。在其他项目中，我们正在调查 小脑在眼动准确能力中的作用 在某些事情使他们不准确之后。小脑一直是 牵涉到无意识的李尔宁，它让我们保持动作 准确，但我们不知道它起到了什么作用。1998年，我们发布了 描述了如何使许多重复的快速眼球 动作会影响这些动作的表现。这会有帮助的 我们正确地解释了我们收集的眼动适应数据 从猴子那里。我们还发表了两篇摘要。其中一个描述了 小脑的一个特殊部分，即后部的作用 间位核，眼球运动顺畅。小脑是 对于这些流畅的动作至关重要。这项工作将告诉我们这是什么 小脑的一部分起作用。另一个摘要描述了一个 两种快速眼动的区别。小脑 对这两种运动的影响是不同的。 它们之间的差异告诉我们关于小脑功能的信息。 NIH拨款EY00745和EY10578，并由德意志银行提供资金 Foschungsgomeinschaft(Heisenberg-Program Str 436/1-1)。*Straube，A.

The goal of this research is to understand how the cerebellum aids eye movements. We know that the cerebellum is important in every movement we make, but we do not know exactly what it does or how it does it. We can make progress faster by investigating the cerebellum with eye movements than with limb or other movements because we know much more about how the brain produces eye movements than any other movements. Our results will also help us understand how the brain produces eye movements. Eye movements are an important part of our lives. Every day we make tens of thousands of eye movements to look at things of interest and see them clearly. Abnormalities in eye movements severely reduce our ability to read, see, and visually guide our other movements. Among other projects, we are investigating the role of the cerebellum in the ability to make eye movements accurate after something has made them inaccurate. The cerebellum has been implicated in the unconscious lear ning that keeps our movements accurate, but we do not know what role it plays. In 1998 we published a description of the way in which making many repeated rapid eye movements affects the performance of these movements. This will help us correctly interpret data on eye movement adaptation that we collect from monkeys. We also published two abstracts. One describes the role of a particular part of the cerebellum, the posterior interpositus nucleus, in smooth eye movements. The cerebellum is critical for these smooth movements. This work will tell us what this part of the cerebellum contributes. The other abstract describes a difference between two kinds of rapid eye movements. The cerebellum contributes a different influence to these two kinds of movements. The difference between them tells us about cerebellar function.
