Table 4. A summary of fitting parameters for the analysis of the maximal slope of ERG b-wave rising phase as function of flash intensity.
| Ihalf [cd·s/m2] | Smax [µV/ms] | n | |
| RGS9 +/+ | 0.0085±0.0012 | 21.8±0.4 | 0.65±0.06 |
| RGS9 −/− | 0.0151±0.0026 | 27.7±0.5 | 0.65±0.06 |
| R9AP +/+ | 0.0209±0.0024 | 20.8±0.3 | 0.68±0.04 |
| R9AP −/− | 0.0551±0.0029 | 27.4±0.2 | 0.63±0.02 |
The data were fitted using Equation 3 (see Materials and Methods); Ihalf is the half-saturating flash intensity, Smax is the asymptotic value of the maximal slope at saturating flash intensities, and n is the Hill coefficient (mean ± SEM).
