OFF OS RGC is a distinct functional cell type. a Responses of OFF OS (left) OFF sustained alpha (middle) and OFF transient alpha (right) RGCs to a 1 s flash of 200 μm diameter circular light spot from darkness. Yellow rectangle indicates light stimulus. b Peak firing rate at light offset plotted against mean baseline firing rate for OFF OS (n = 92) and non-OS (n = 84) RGCs. Dotted lines indicate peak firing rate = 135 Hz and mean baseline firing rate = 50 Hz. c Dendritic morphology of two neighbouring OFF OS RGCs. Scale bar = 50 μm. d, e Polar plots of drifting grating responses of OFF OS RGCs coloured in green (d) and (e) orange, respectively. F1 response amplitudes and grating angles are plotted in radial axes and angle axes, respectively. F1 cycle average responses are calculated from three trails in each angle. f Histogram of OSI of OFF OS (n = 92) and non-OS RGCs (n = 84) as identified by their light step response profile. Dotted line indicates OSI = 0.2. g Angle histogram of preferred orientations of OFF OS RGCs recorded in WT retina (black, n = 78) or labelled cells in the JAM-B line (green, n = 14). Dotted line indicates 45° angle
