Receptive field properties of horizontal cells in the tiger salamander retina: contributions of rods and cones.
The spatial properties of horizontal cells in the tiger salamander retina were studied with intracellular electrodes. It was found that when the rod input to horizontal cells is dominant the receptive fields are smaller than those measured under conditions of strong cone activation. A possible explanation for this finding is that rod signals undergo greater lateral attenuation within the horizontal cell network.
