Fig. 4: Effect of target–distractor separation.
From: Spatial contextual effects in primary visual cortex limit feature representation under crowding
a Across trials, we varied the spacing of targets and distractors, from distant (3.28° center-to-center distance, pink) to near (1.06°, red). Trials were randomly interleaved. b Average thresholds for responses to targets with distractors, normalized to thresholds for targets alone. Error bars represent s.e.m. across populations. Source data are provided as a source data file.
