Figure 5.11 : Response of the rod network to spatial frequencies in two directions. Rod
diameter a = 10 μm and cell spacing D = 16 μ m. Diagonal represents equal x and y
frequencies. (A) Spatial frequency response in the coupled salamander retina. (B) Spatial
frequency response in uncoupled rod photoreceptors.
