Neonatal enucleation induces an asymmetric pattern of visual callosal connections in hamsters.
Autoradiography and the horseradish peroxidase (HRP) technique were used to investigate visual callosal connections in normal hamsters and in animals which had one eye removed at birth. In normals and in the cortex contralateral to the remaining eye in the neonatal enucleates, callosal cells and terminal labeling were restricted to the region around the area 17-18a border. In the cortex ipsilateral to the remaining eye in the neonatal enucleates labeled cells and terminal labeling were observed throughout areas 17 and 18a.
