Figure 6.

Experimental (gray traces, noisy) and simulated (black traces, noiseless) step photocurrents measured at −40 mV in three different dark-adapted bass single cones. (A) Intensities tested were 171, 773, and 8,770 VP*/s. (B) Intensities tested were 50, 963, and 10,320 VP*/s. (C) Intensities tested were 50, 963, 10,320, and 41,466 VP*/s. The values of the parameters used in the simulations shown are listed in Table 4. (D) A time-expanded view of the end of the response to 41,466 VP*/s shown in C. At this intensity, photocurrent amplitude was saturated. The unsuccessful simulations illustrated in red were computed when ${\gamma }_{\max }$ was kept at the same value used to fit the responses to dim stimuli.
