Cognitive and sensory basis of motor learning

该提案要求为正在进行的关于人类自主运动的神经控制的研究提供资金。我的研究重点是研究自主肢体运动的中枢控制信号组织，以及运动学习和感觉-运动适应的神经、认知和感觉机制。实验和模型研究的结合被用来检验关于多关节肢体运动如何被控制以及运动学习如何实现的假设。本提案中概述的研究分为两个主要主题：(1)理解上下文在运动学习中的作用；(2)运动学习对感觉系统的影响。这项研究的结果将大大增加我们对运动系统如何组织以及运动和感觉系统如何相互作用的认识。这类知识可能有助于未来理解脑损伤中感觉-运动缺陷的基础，并可能有助于感觉-运动康复的合理方法。

This proposal requests funds for ongoing research into the neural control of human voluntary movement. The focus of my research program is to study the organization of central control signals for voluntary limb movement, and the neural, cognitive and sensory mechanisms underlying motor learning and sensory-motor adaptation. A combination of empirical and modeling studies are used to test hypotheses about how multi-joint limb movements are controlled and how motor learning is achieved. The studies outlined in this proposal are organized in two major themes: (1) Understanding the role of context in motor learning and (2) Effects of motor learning on sensory systems. The results of this research will add significantly to our knowledge of how the motor system is organized and how motor and sensory systems interact. This kind of knowledge may be useful in future efforts to understand the bases of sensory-motor deficits in brain damage, and may contribute to rational approaches to sensory-motor rehabilitation.
