In recent years, the zebrafish larva has become a powerful vertebrate model for neuroethology research. Its optical accessibility, a known genome and a vast library of promoters and mutants, make the zebrafish specially suitable for optogenetics and cutting-edge optical methods (e.g. light-sheet microscopy, holographics) to monitor and manipulate neuronal activity. In addition, the zebrafish has a complex although discrete repertoire of motor behaviours, making an ideal vertebrate preparation for the study of neuronal circuit dynamics underlying motor behaviour. The purpose of this meeting is to bring together researchers interested in the study of neural circuits and behaviour, and to introduce the zebrafish model to the neuroethology community which allows the use of state-of-the-art technical approaches to ask neuroethological questions and test specific hypotheses with unprecedented power and infeasible using other animal models.
