Figure 1. Differences in regenerative ability of the central nervous system through species and aging. In contrast to zebrafish that maintain their neuroregenerative capacity throughout adulthood, killifish completely lose this ability upon aging and do not functionally recover from central nervous system damage. As such, with age, the regenerative response of the killifish central nervous system switches to one that resembles (young) adult mammals.
