Temporal interactions of dorsal/ventral visual streams.

本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不同于与朝向物体的运动相关的神经通路，但这两种皮层视觉流的激活速度和相互作用尚未研究。该项目将使用神经科学脑成像技术（MEG，EEG，fMRI）的时间敏感性来测量目标导向抓取过程中两个视觉流之间的实时交互序列。它旨在通过发现这些通路“何时”激活和相互作用来扩展最有影响力的视觉处理模型。这些知识将影响社会和商业成果的交付，为许多神经发育障碍的感觉运动性能的康复提供新的方向，并通过改进机器人效应器，假肢和更无缝的人机界面的控制系统的设计。

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.
