Abstract

In siamese cats, each side of the brain receives a retinal input serving part of the ipsilateral visual field as well as the normal contralateral field representation. Both corticothalamic and cortico-cortical projections are systematically rearranged, but while one is retinotopically appropriate, the other fails to make a distinction between ipsilateral and contralateral fields. Different rules appear to govern the development of these two sets of connections.
