The increasing number of genetic tools available for the African cichlid Oreochromis mossambicus (Mozambique tilapia), together with the emerging interest in its use for neurobiological studies, increased the need for an accurate mapping of the tilapia brain. Our goal was to elaborate a T2-weighted 3D-digital atlas using magnetic resonance imaging on perfused tilapia brain. Resulting images enabled accurate segmentation of most brain nuclei in the olfactory bulb, telencephalon, diencephalon, optic tectum and cerebellum. This tilapia brain atlas is expected to become a very useful tool for neuroscientists using this fish model and will certainly expand their use in future studies.
