Abstract

Saccades curve away from locations of previous fixation. Varying stimulus timing demonstrates the effects of both 1) spatiotopic representation and 2) motor residual activity from previous saccades. The spatiotopic effect can be explained if current models are augmented with an excitatory top-down spatiotopic signal.
