Table 1.

Fitting parameters for in vivo ERG recordings and statistical analysis of the differences among selected groups

Rmax, maximal response amplitude (μV); I0.5, half-saturating light intensity (cd·s/m2); n, Hill coefficient. Four eyes of two mice of each genotype were recorded for P22 and P36, and six eyes of three mice of each genotype were recorded at P47. p values were calculated to determine the statistical significance between the curve fits for each genotype using an F test. KO, knockout.
