Spatiotopic neural representations develop slowly across saccades

One of the long-standing unsolved mysteries of visual neuroscience is how the world remains apparently stable in the face of continuous movements of eyes, head and body. Many factors seem to contribute to this stability, including rapid updating mechanisms that temporarily remap the visual input to compensate for the impending saccade [1]. However, there is also a growing body of evidence pointing to more long-lasting spatiotopic neural representations, which remain solid in external rather than retinal coordinates 2, 3, 4, 5 and 6. In this study, we show that these spatiotopic representations take hundreds of milliseconds to build up robustly.
