Reaching to grasp an object represents a motor activity we perform on a daily basis usually without perceivable effort or conscious thought. However, even this simple action requires the delicate coordination of multiple resources within our central and peripheral nervous systems. Moreover, these resources continually seek out new and optimal ways to improve the efficiency and effectiveness of our movements. Hence, the projects associated with this grant seek to understand the sensory, cognitive and motor mechanisms that contribute to our ability to regulate skilled actions. For example, what information from our visual world is used to control reaching and grasping movements, and what regions of the brain process this information? Do anatomical properties of the human eye impact the production of fast and accurate movements to different regions of visual space? How does our sense of body position contribute to the successful planning and control of skilled movement? Ultimately, answers to the aforementioned questions may assist engineers in the design of optimal human-machine interfaces and may provide the requisite knowledge-base for the development of intervention programs circumventing movement difficulties associated with acquired and developmental movement disorders.

伸手去抓一个物体代表了我们在日常基础上进行的一种运动活动，通常没有可感知的努力或有意识的思考。然而，即使是这个简单的动作也需要我们中枢和周围神经系统中多种资源的微妙协调。此外，这些资源不断寻找新的最佳方法来提高我们运动的效率和效果。因此，与这项资助相关的项目寻求理解有助于我们调节熟练动作的感觉、认知和运动机制。例如，我们视觉世界中的哪些信息被用来控制伸手和抓握的动作，大脑的哪些区域处理这些信息？人眼的解剖特性是否会影响视觉空间不同区域快速准确运动的产生？我们对身体位置的感觉是如何帮助我们成功地规划和控制熟练的动作的？最终，上述问题的答案可以帮助工程师设计最佳人机界面，并为开发干预程序提供必要的知识基础，以避免与获得性和发展性运动障碍相关的运动困难。
