FIGURE 2.

Rod responses to 20-ms flashes of 500-nm light for Grb14^−/− and control rods under dark-adapted and bleach-adapted conditions. A, dark-adapted WT strain control at light intensities of 2.4, 8.0, 21, 70, 122, 220, 403, 733, 1430, and 2600 photons μm⁻². Traces are mean responses from 22 rods. B, responses of WT rods after 50% bleach. Light intensities were 70, 220, 733, 2600, 8620, and 22,700 photons μm⁻². Traces are mean responses from 11 rods. C, flash responses for dark-adapted Grb14^−/− at the same light intensities used for the dark-adapted WT rods. The traces are the mean of 10 rods. D, Grb14^−/− flash responses after 50% bleach at light intensities of 70, 122, 220, 403, 733, 1430, 2600, 4730, and 8620 photons μm⁻². Traces are the mean responses from 10 rods. Data in this and subsequent figures were acquired at 100 Hz and Bessel-filtered at 35 Hz.
