(A and C) Representative response-weighted stimulus response profiles of excitatory input to ONα-RGCs in conditions preferentially activating rods (A, mean intensity: 1.5 R*) and in conditions preferentially activating cones (C, mean intensity: 1,500 R*) recorded in wild-type (grey) and B6-DTA (pink) retinas. (B and D) Summary data (mean ± SEM) of temporal frequency-response functions computed from Fourier transforms of response-weighted stimulus response profiles in conditions preferentially activating rods (B, WT: n = 9, grey; B6-DTA: n = 8, pink) and in conditions preferentially activating cones (C, WT: n = 17, grey; B6-DTA: n = 17, pink).
