title: A note on the relative rates of degeneration in the crossed and the uncrossed retinofugal fibres in the opossum Didelphis marsupialis.
abstract: The rates at which the crossed and the uncrossed components of the retinofugal pathway degenerate in Didelphis has been studied by light and electron microscopical methods. We have found that in Didelphis, as in Monodelphis the two components can be clearly distinguished at the level of the chiasm. However, in contrast to the situation previously described for Monodelphis, where the uncrossed component degenerates more rapidly than the crossed, both components degenerate at the same rate.
