Behavioral paradigms. (A) Coarse, left–right, global direction discrimination task used to train subjects and measure direction range thresholds. (B) Fine direction difference thresholds were collected at different levels of direction range by presenting a random dot stimulus within the blind field, which moved slightly above or below the horizontal meridian. (C) Sample visual field of a subject in the present study. Blue circles indicate locations where performance was mapped in order to select a training location (red circle).
