Visual Neuroscience

人类的手是一项了不起的工程。我们人类可以伸出手来，精确地抓住物体--比任何机器人都要好。使这成为可能的因素之一是我们敏锐的视觉。Mel Goodale教授和他的团队正在研究我们的视觉系统用来指导手伸出手来抓住物体的不同类型的信息，以及这些信息与用于识别物体和识别场景的信息有何不同。Goodale教授还使用功能性磁共振成像（fMRI）来探索大脑的哪些部分参与了眼手协调和视觉识别。这项工作不仅提供了关于如何使用视觉来控制人手的基本信息，而且还有助于设计更好的控制机器人手的系统。

The human hand is a remarkable piece of engineering. We humans can reach out and grasp objects with exquisite accuracy - far better than any robot. One of the things that make this possible is our keen sense of sight. Prof. Mel Goodale and his team are studying the different kinds of information that our visual system uses to guide the hand as it reaches out and grasps an object and how that information differs from that used to identify objects and recognize scenes. Prof. Goodale also uses functional magnetic resonance imaging (fMRI) to explore which parts of the brain are involved ineye-hand coordination and visual recognition. This work is not only providing basic information about how vision is used to control the human hand but is also helping in the design of better systems for controlling robot hands.
