| summary | Detailed vision is afforded by moving the eyes around a scene. Virtually all high-level vision is therefore based on multiple retinal images that can differ greatly. One way the visual system may compensate for these changes is by remapping or realigning retinal images based on an internal copy of the eye movement, thus locating objects in a spatiotopic reference frame. Human observers are notoriously poor in trans-saccadic spatiotopic tasks, however sub-threshold spatial errors lead to oculomotor plasticity, suggesting accurate spatiotopic realignment. I will present studies examining the spatial limits of remapping and the relationship between remapping and oculomotor plasticity. These studies suggest that internal copies of eye movements may be used separately for perception and action. |
