We are a research laboratory at the Ecole Normale Supérieure in Paris aiming to unravel how the nervous system processes cognitive functions and controls animal behaviour, the laboratory uses the zebrafish larva as the experimental model and a multidisciplinary approach, including two-photon calcium imaging to monitor activity of large neuronal networks, motor behaviours,  genetic engineering techniques to label, monitor and manipulate neuronal activity  and mathematical methods for data analysis. It is the combination of disciplines, and the use of a behaving animal model that enables deciphering complex neuroethological questions such as perception of time, decision making, learning & memory and sensory perception.
