Figure 2.

Perisaccadic sensitivity. Left four panels show data for contrast modifications in the 0.375–0.75 cpd band; right two panels show data for the 1.5–3 cpd band. Symbols denote bins of 100 trials; solid lines are the best-fitting asymmetric Gaussians. In the active condition (dashed line, triangles), subjects freely made eye movements; in the passive condition (solid line, circles), the same retinal input was replayed by shifting the video while subjects maintained central fixation. Sensitivity was impaired during both active and passive saccades. When contrast increments were presented immediately after saccades (t > 0), sensitivity was enhanced compared to the passive condition.
