Illustration of flanking suppression by SCRI in a display containing a target and seven distractors. Spiking activity for distractors near the target is lower than for distractors farther from the target. Simulated activity is averaged over SCRI fits to cells recorded under set size manipulations. Set size manipulations enabled us to estimate the spatial distributions of FEF and identification-unit lateral inhibition. These forms of inhibition lead to flanking suppression.
