This project will rely on behavior analysis of zebrafish larvae exploring in neutral conditions as well as animals exposed to chemical gradients. Chemosensory integration in peripheral sensory organs modulates the activity of motor centers in the brain in order to change direction, speed and sequences of bouts during exploration. This PhD project will unravel the algorithm deployed by zebrafish larva to navigate and the underlying neuronal circuits using population imaging, genetics, optogenetics, and in vivo electrophysiology in order to build an integrated circuit model of zebrafish navigation.
