Temporal retina is preferentially represented in the early retinotectal projection in the hamster

Retrograde transport of horseradish peroxidase (HRP) after complete transection of the brachium of the superior colliculus on the day of birth in hamsters revealed preferential labelling of the temporal retina. Cytochrome oxidase staining of the retina showed similar preferential temporal labelling. A discrete lack of label of the extreme temporal periphery of the retina contralateral to the HRP placement and a complementary label of ipsilateral temporal periphery were also observed.
