An autoradiographic study of the retinofugal projections in the shark, Hemiscyllium plagiosum.
The retinofugal projections in the shark, Hemiscyllium plagiosum were studied after unilateral eye injection of tritiated proline. The results showed that each eye in this animal projects not only to the contralateral side of the brain but also to several ipsilateral visual centers including the nucleus suprachiasmaticus, ventrolateral nucleus of the optic tract and the optic tectum. These results suggest that some of the visual centers in this animal receive direct retinal inputs from both eyes as is the case in many other animals and most notably in mammals.
