To be able to grasp and manipulate objects, we need to know not only their location, but also their shape, orientation and size. Visual information about such properties determines the anticipatory posture of the hand and fingers during reaching, and is critical for controlling skilled actions such as precision grip1. But the neural representations of shapes may be different from the representations that mediate the visual control of action. For example, although object recognition relies on representations that do not vary with changes in orientation, location and size, to act on these objects we probably need representations that are sensitive to just such changes.
