Gross anatomy of the archer fish brain

Archer fish feed on insects above water level that they knock down with a shot of water from their mouth. This exceptional ability is possible thanks to a sophisticate visual system. The archer fish is an excellent animal model for many questions in neuroscience since it can learn to distinguish between artificial targets presented on a computer monitor. Thus, the archer fish can provide the fish equivalent of a monkey or a human subject that can report psychophysical decisions and make controlled and complex experimental procedures possible. However little is known about the archer fish brain structure and anatomy. For this reason we produce a topological atlas of the archer fish brain and provide comparison with other teleost. This enables us to identify and analyze specific cerebral structures involved in vision and participating in decision making by the archer fish during predation.
