Figure 6.

Dark event rates per rod as a function of the fraction of A2 pigment A, the estimates of dark event rates of all 5 rods in Table 1 in the native and final states plotted against the fraction of A2 pigment. The red line shows the linear regression of event rate (y) on A2 content (x): y = 0.0009 + 0.318x. All event rates have here been normalized to the mean outer segment (OS) volume recorded in our experiments (2100 μm³), thus correcting for volume differences in the individual recordings. B, the same data as in A shown on logarithmic scales.
