Olfaction has long been considered as a « secondary » sensory modality but recent discoveries highlighted its central role in brain functions. During the first session of this symposium, the neurobiological bases of olfactory learning from the early stages of life (Coureaud, Sullivan) to adulthood (Busquets-Garcia, Nicole) will be illustrated. The second session will primarily focus on the physiology of the first relays of olfactory information processing, namely the olfactory bulb and the piriform cortex (or homologous structures in Drosophila), as well as their strong interactions (Nissant, Plaçais, Martin and Wilson).
