Coding and memory in olfaction
Neural bases of olfactory experience
The perception of an odor, our ability to recognize it, to distinguish it even from a very similar one, results from our daily olfactory experience. This axis brings together research projects aimed at understanding how olfactory representations are built up across successive odour experiences and how they may, in turn, modulate odor perception and recollection of associated information.
Project 1 : Simple forms of associative memories (Barbara Ferry, Nicolas Kuczewski, Anne-Marie Mouly)
Project 2 : Olfacto-tactile multisensory associations (Barbara Ferry, Rémi Gervais)
Project 3 : A complex form of associative memory : episodic memory (Jane Plailly, Nadine Ravel, Jean-Pierre Royet, Damien Gervasoni)
