Multiple efferent systems project to the retina in three species of teleost fish investigated with the horseradish peroxidase technique. These animals are the first vertebrates shown to have more than one central nervous system structure projecting to the retina. The connections discovered may reflect a primitive organization of retina-brain interconnections.
