An electrophysiological study of early retinotectal projection patterns during regeneration following optic nerve crush inside the cranium in Hyla moorei.
The sequence of regeneration following intracranial optic nerve crush has been studied using electrophysiological visual mapping in the frog Hyla moorei. Compared to our earlier series with extracranial crush, the time course was slower and the intermediate projections more disorganized. It is suggested that the apparent discrepancy between the early patterns of regeneration in Xenopus and Rana compared to Hyla, fish and newt, is not due to species differences but to the location of the lesion site.
