Fig. 5: How distractors affect V1 neuronal responses to targets.

a Effect on responsivity. Histogram shows the response modulation index (the average response to targets with distractors compared to targets alone). Shaded black tails indicate cases with particularly strong suppression (index ≤ 0.5) or with facilitation (index ≥ 1). Open arrowhead indicates mean. b The Fano factor for targets with distractors, relative to targets alone. Open arrowhead indicates mean. c Single neuron discriminability (area under ROC curve) for target stimuli separated in orientation by 20 degrees, for targets alone and with distractors. Unity line shown in black; red line represents linear regression line. Source data are provided as a source data file.
