Light-induced changes in the photoreceptor tip-HB magnitude of C57/Bl6J mice. (A) HB magnitudes measured for each mouse eye before (baseline in dark) and after 80-s bright light stimulation. There is a significant increase (P < 0.01, n = 7) of HB magnitudes after light stimulation. (B) Time course of off kinetics for HB magnitudes. Duration of light stimulation [bright (n = 4): 1 × 104 cd/m2; dim (n = 5): 219 cd/m2] is shown as the bottom trace. *, significant (P < 0.05) difference for values measured after bright and dim light stimulation.
