Figure 3. Rod responses to 20-ms flashes of 500-nm light for IR knock-down and control rods under dark-adapted and bleach-adapted conditions.

(A), dark-adapted WT strain control at flash intensities of 2.6, 8.6, 23, 75, 130, 236, 430, 783, 1530, and 2780 photons µm⁻². Traces are mean responses from 21 rods. (B), WT rods after 50% bleach. Flash intensities were 75, 236, 783, 1530, 2780, 5050, and 9190 photons µm⁻². Traces are mean responses from 9 rods. (C), dark-adapted IR knock-down rods at same flash intensities as in A. Traces are mean responses from 16 rods. D, IR knock-down (IR-KD) rods after 50% bleach. Flash intensities were same as in C. Traces are mean responses from 8 rods.
