Research Theme

Research in the team focuses on the cellular and molecular mechanisms of learning and memory and on identifying mechanisms responsible for memory dysfunction in brain pathologies. Our objective is to identify in different structures of the brain such as the hippocampus and cortex the cellular and molecular mechanisms underlying brain of plasticity, to characterize their role in the formation of memories and identify networks and brain structures within which these changes occur during the laying down of memories. Our approach, from genes to function, leads to both the identification of cellular and synaptic changes linked to learning and to the functional characterisation of the role of signalling cascades, transcription factors, and the regulation of genes and proteins underlying different phases of plasticity and forms of memory. The research projects cover different facets of plasticity and memory, ranging from synaptic mechanisms to neurogenesis, complemented by the analysis of the cellular and molecular mechanisms of memory dysfunction associated with pathologies of genetic origin such as mental retardation or neurodegenerative diseases such as Alzheimer's disease. In these animal models, we explore the potential of genetic, pharmacological or behavioural therapies. The research is based on multidisciplinary approaches including cellular and molecular biology, biochemistry, functional neuroanatomy and imaging, pharmacology, in vivo electrophysiology and behavioural analyses of learning and memory in rats and genetically modified mice.
