Using the zebrafish larva as the experimental model and a multidisciplinary approach, including twophoton calcium imaging to monitor activity of neural networks, motor behaviours, genetic engineering techniques to label, monitor and manipulate activity of specific neurons or entire circuits and mathematical methods for data analysis, we are studying the following subjects:

1) Multimodal sensory perception:

The optic tectum has emerged as a tractable visuomotor transformer, in which anatomical and functional studies can allow a better understanding of how behavior is controlled by neuronal circuits. We are examining the formation and function of the visual system in zebrafish larvae using in vivo time-lapse microscopy and state-of-the-art “connectomic” and “optogenetic” approaches to monitor and perturb neuronal activity. We apply complementary cellular and molecular analyses to dissect this circuit and identify the neuronal substrate of visual behaviors.

Le traitement de l’information par le cerveau et la rétine repose sur des assemblages extraordinairement complexes et précisément organisés de neurones et cellules gliales. Le développement de ces réseaux pose deux questions majeures : comment les cellules qui les composent sont-elles générées en nombre et types adéquats ? Comment ces cellules se répartissent-elles dans le tissu nerveux et s’interconnectent-elles ?
