a Response profiles of example excitatory and inhibitory neurons to SFGs with 5 different orientation contrasts in two backgrounds. Gray shade indicates the SD across 5 trials. Blue and red arrows mark the onset and offset of visual stimuli, respectively, while gray arrows mark the phase shift of the gratings. Red lines indicate the baseline activity without visual stimulation. Scale: 30% ΔF/F0, 0.5 s. b Violin plots for response amplitudes to different orientation contrasts for saliency-encoding neurons with OSI < 0.25 (left, N = 101) and OSI ≥ 0.25 (right, N = 37). c Violin plots for the difference in response amplitudes elicited by SFGs of 30° and 90° contrasts for saliency-encoding neurons, plotted against different levels of orientation selectivity. Low: OSI < 0.25; High: OSI ≥ 0.25, t-test. d, e The same plots for inhibitory neurons. Left, N = 121; Right, N = 53.
