The flicker sensitivity (temporal modulation transfer function) of a rod monochromat was measured at luminances in the range of 8 to 782 scotopic td. The results could be fitted by a single curve shifted vertically, suggesting that rod saturation is independent of the temporal properties of the stimulus. This is consistent with the hypothesis that rod saturation is a pure receptor phenomenon.
