Not only can fish regenerate, but most fish (those with indeterminate
growth) continue to generate neurons throughout life...  There is a
reasonably sized literature on this topic.  You should start by search
through the work of Pamela Raymond Johns and Steve Easter.  They deal
primarily with the visual system, but it serves as an excellent example.
In my work I have looked at cell birth throughout the brain (and it occurs
widely), but I have not yet published any of it.

Cheers - Matthew
