The spot outer diameter that elicited the maximum spiking response for ON and OFF GCs is an estimate of the RF center diameter for each genotype. The mean RF diameter (x̄), ±SE, and total number (n) of cells are presented for each genotype. RF dimensions are corrected for monitor distance and are presented in degrees of visual angle.
