[Autoradiographic analysis of retinal projections in the flatfish Scophthalmus maximus L]

The organization of retinal projections were examined in the flatfish Scophthalmus maximus using the autoradiographic technique. Overall 15 different contralateral primary optic centers were identified at hypothalamic, thalamo-pretectal, tectal and tegmento-mesencephalic levels. A weak ipsilateral retinal contingent was also observed. Elsewhere, the retinal projections of the migrating eye in comparison to those of the non-migrating eye were observed to be similar.
