Photopic a-wave amplitudes. (a) Amplitudes of photopic ERG a-waves plotted as a function of flash intensities. (b) Scatter plot for normalized a-wave amplitude as a function of flash intensity in AM251-injected monkeys. Grey points indicate raw values; red data points with error bars indicate the mean and standard error of the mean. (c) Scatter plot and linear regression for normalized a-wave amplitude as a function of flash intensity in AM630-injected monkeys. Grey points indicate raw values; blue data points with error bars indicate the mean and standard error of the mean. (d) Main effect of average amplitudes across intensities in AM251 (red) or AM630 (blue) groups. ^∗ p < .05.
