The first part of this thesis presents an historical overview of neural recording techniques, followed by a study on the development of a new imaging method for zebrafish neural recording: two-photon light sheet microscopy. Combining the advantages of two-photon point scanning microscopy and light sheet techniques, the two-photon light sheet microscope warrants a high acquisition speed with low photodamage and allows to circumvent the main limitation of one-photon light sheet microscopy: the disturbance of the visual system. The second part of the thesis is focused on goal-directed navigation in zebrafish larvae. After an exhaustive review on chemotaxis, phototaxis and thermotaxis in various animal models, we report a study that reveals the...
