This project aims to understand the temporal interactions between the dorsal and ventral visual streams that control skilled actions. The neural pathways for visual perception of objects may be distinct from those associated with movements towards the object, but the speed of activation and interactions of these two cortical visual streams have not been investigated. This project will use the temporal sensitivity of neuroscience brain imaging techniques (MEG, EEG, fMRI) to measure the real-time sequence of interactions between the two visual streams during goal-directed grasping. It intends to extend the most influential model of visual processing by discovering ‘when’ these pathways activate and interact. Such knowledge will affect delivery of social and commercial outcomes, by providing new directions for the rehabilitation of sensorimotor performance in many neurodevelopmental disorders, and by improving design of control systems for robotic effectors, prosthetic limbs, and more seamless human-machine interfaces.

这个项目旨在了解控制熟练动作的背侧和腹侧视觉流之间的时间相互作用。视觉感知物体的神经通路可能与朝向物体的运动相关的神经通路不同，但这两种皮层视觉流的激活速度和相互作用尚未被研究。这个项目将使用神经科学大脑成像技术(脑磁图、脑电、功能磁共振成像)的时间敏感性来测量目标定向抓取过程中两个视觉流之间相互作用的实时序列。它打算通过发现这些通路何时激活和相互作用来扩展最有影响力的视觉处理模型。这些知识将通过为许多神经发育障碍的感觉运动能力的康复提供新的方向，并通过改进机器人执行器、假肢和更无缝的人机界面的控制系统的设计，来影响社会和商业成果的交付。
