a Circular and square drifting grating stimuli, b their evoked maps of maximal calcium response, c maps of OS pixels (pixel size: 7 µm; color-coded by preferred orientation) and histograms of preferred orientation for all OS pixels in the imaging field of view. d Distributions of preferred orientations for the ROIs 1–6 from the 5 OS maps in (c). Orientation selectivity parameters, e FWHM, f, g gOSI and OSI, h, i gDSI and DSI for the 30 OS ROIs in (c) across the five different stimuli. ns no significant difference in parameter distributions across the five stimuli; p > 0.05, Kruskal–Wallis test. Error bars: 25 and 75 percentiles; Red lines: median. Source data are provided as a Source Data file.
