Research interests

The main objective of my research is to identify mechanisms of plasticity in the adult brain that underlie memory. Using rodent models (rats and transgenic mice), I previously asked how different key mechanisms of plasticity, such as noradrenalin, Collapsin Response Mediator Proteins, estrogens, the Immediate Early Gene Zif268/Egr1 and the formation of new neurons in the adult olfactory bulb and hippocampus, contribute to specific phases and processes of memory (learning, recall and consolidation).
Recently, I focused my attention on a complex from of memory ; the episodic memory which is characterized by the encoding, consolidation and recollection of unique past experience, including “What” happened, “Where” and “When-In which context”. In collaboration with Serge Laroche Lab (CNPS, CNRS UMR8195, Université Paris-Sud XI, Orsay) and colleagues working in Humans in the team, we have developed a novel framework and paradigm that provides means to evaluate, in a situation as close as possible to the paradigm developed in Humans, the ability of rats to form and recollect a combined long-term episodic-memory of odors (What) encountered in distinct locations (Where) in given multisensory enriched environments (In Which context).
This paradigm offers us the possibility to investigate genetic, molecular, neurophysiological mechanisms and network dynamics that underlie encoding and faithful recollection of past events.
