Abstract
- When one tectum of an adult goldfish is removed, the severed retinal fibers regenerate ipsilaterally into the remaining tectal lobe. Initially fibers from the two eyes overlap in the tectum but EM-HRP data suggest that few mature retinal synapses are formed between the ipsilateral eye and tectum at this time. At longer time periods, when some fibers appear to segregate into eye-specific termination bands, our data suggest that a significant number of synapses from the ipsilateral eye are present. These findings have important implications for how eye-specific termination bands are formed in doubly innervated tecta.
