In the original version of this paper, the color map in Figure 1D in the superior colliculus was reversed from what it should be. The authors also noticed that the color scheme in Figure 1D may be misunderstood as being the same as that of Figure 1A. These have now been corrected online to show the appropriate visual field representation maps across superior colliculus and visual cortex. The scale has been relabeled to clarify that the coordinates refer to the visual field location. The authors apologize for the error.
