A central and unified role of corticocortical feedback in parsing visual scenes.

In the late epoch, V4 ablation significantly reduced surface facilitation and background inhibition, while the reduction in edge facilitation did not reach statistical significance (Fig. 6j , lower vs. upper row; Fig. 6k , upper, red vs. gray: left, edge facilitation, p = 0.087, 43.1% decrease; middle, surface facilitation, p = 0.0028, 46.6% decrease; right, background inhibition, p = 3.8 × 10 −7 , 72.2% decrease).
