Deletion of PKCα changes the ERG b-wave evoked by bright flashes. (A) Electroretinograms b-waves evoked by bright flashes collected from WT (n = 62, black) and KO (n = 52, red) eyes were averaged and plotted versus postflash time after OPs were filtered out. Numbers at the lower left of the traces represent flash strength in log(cd-s/m²). (B) The b-wave FWHM of the average ERGs from WT (black) and KO (red) eyes are plotted (mean ± SEM) versus light intensity. (C) The times to reach half of the b-wave peak amplitude were calculated from the average ERGs of WT (black) and KO (red) eyes and plotted (mean ± SEM) versus light intensity. (D) The b-wave implicit times of the averaged ERGs from WT (black) and KO (red) eyes are plotted (mean ± SEM) versus light intensity.
