The mature nervous system is an intricate network in which neurons are connected to specific partners. The choice of these partners is crucial for the correct behavior of the network (meaning the nervous system) and is determined at early stages of development. Abnormal development of neuronal connections is responsible for a large range of neuronal pathologies, some of them affecting vision. Research carried on by our team focuses on a better understanding of the development of sensory maps including the connection between the retina and the brain.
