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...

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 functions in the laboratory animals over last decade, however the interests in the behavioral features of zebrafish are limited. In contrast to zebrafish, the cognitive function for cavefish (Astyanax mexicanus) is based on mechanosensory systems and their lateral line, which is highly sensitive to fluctuating water movement and pressure. Many evolution researches have been done to these cavefish reported that they have better olfactory sense by having taste buds all over its head which help them find food more quickly in complete darkness. In addition, the mechanosensory lateral line system helps them to perceive their environment. While rodents have traditionally been used to study cognitive and memory functions, the zebrafish are gaining popularity as an excellent vertebrate model to complement current translational neuroscience research.
