I am interested in sensory information processing in the mammalian brain. My goal is to decipher how odor-reward association could be encoded at early stages in the olfactory system during learning processing. By using a combination of behavior, imaging and optogenetic approaches my project seek for a causal relationship between the controlled activity of genetically defined neural cell types and particular animal behaviors. My work is mainly focus on the functional role of newborn neurones in the adult and postnatal olfactory system.
