Developing a model for studying complex brain function using zebrafish (Danio rerio) and cavefish (Astyanax mexicanus)

The zebrafish (Danio rerio) has been used as a model organism for studies in developmental biology. In fact, several common and important developmental genes mechanisms have been identified in zebrafish, which are similar in mammals. There is also growing research in the cognitive and memory functio...
