DESCRIPTION (provided by applicant): The network of investigators proposed here will explore how problem solving activities engage different loops and circuits that patch together channels through a cognitive map in the dentate nucleus of the cerebellum. Our proposed activities represent a unique focus on developing tasks and methods for cross-species comparisons, bridge building between anatomical and functional data, and joint consideration of both motor and cognitive functions of the cerebellum. Dr. Strick will generate plans for the construction of an unfolded map of the dentate projections to the cerebral cortex in non-human primates. Dr. Miller will generate plans to study how single unit activity is distributed across this map when monkeys engage in cognitive tasks. The PI, Dr. Houk, will explore conceptual and computational models of signal processing in the modular networks in which the dentate channels participate. Our consultant, Dr. Lewis, will work with Dr. Strick to develop correspondences between molecular staining of human and monkey dentate. Dr. Kim will develop high-resolution imaging methods for exploring human dentate. Drs. Fiez and Reber will formulate plans for using this constellation of tools to document the activation patterns that occur in the cerebellar dentate nucleus when humans are executing problem-solving tasks. Interactions with our consultant Dr. Mesulam will help us explore correlations with neurological disorders and the attentional network spread across the cerebral cortex. Similarly, interactions with Dr. Lewis will help us explore correlations with schizophrenia and other psychological disorders.

描述（由申请人提供）：这里提出的研究人员网络将探索问题解决活动如何参与不同的循环和回路，这些循环和回路通过小脑齿状核中的认知图将通道拼凑在一起。我们提出的活动代表了对开发跨物种比较的任务和方法、在解剖学和功能数据之间建立桥梁以及共同考虑小脑的运动和认知功能的独特关注。斯特里克博士将制定计划，构建非人类灵长类动物大脑皮层齿状投影的展开图。米勒博士将制定计划，研究当猴子从事认知任务时，单个单位的活动如何分布在这张地图上。 PI Houk 博士将探索齿状通道参与的模块化网络中信号处理的概念和计算模型。我们的顾问 Lewis 博士将与 Strick 博士合作，开发人类和猴子齿状细胞染色之间的对应关系。金博士将开发用于探索人类齿状的高分辨率成像方法。博士。菲兹和雷伯将制定计划，使用这一系列工具来记录人类执行解决问题任务时小脑齿状核中发生的激活模式。与我们的顾问 Mesulam 博士的互动将帮助我们探索神经系统疾病和遍布大脑皮层的注意力网络的相关性。同样，与刘易斯博士的互动将帮助我们探索精神分裂症和其他心理障碍的相关性。
