Spectral Sensitivity of Direction‐Selective Ganglion Cells in the Fish Retina

Abstract

In color matching experiments with extracellular recordings from axon terminals of ganglion cells in the tectum opticum of immobilized goldfish, direction-selective ganglion cells were shown to be color-blind. Their spectral sensitivity is determined by a high positive input from the long wavelength-sensitive cones and weak opponent input from other cone types.
