Pretectal neurons project to the salamander retina.
Injection of horseradish peroxidase solution into the eye of some european salamander species labeled retrogradely pretectal neurons. These neurons lie near the commissura posterior and extend their dendrites into the visual pretectal neuropil. On the average, each animal contained 28 labeled cells. Their distribution is bilaterally with a slight preference to the contralateral pretectum. As in other vertebrates these retrogradely labeled pretectal cells may be considered as efferents to the salamander retina.
