Our research addresses the fundamental question of how enduring memories are formed in the brain. We are studying more specifically mechanisms of cerebral plasticity related to spatial and episodic memory in normal mice and in mouse models of memory dysfunctions or pathologies (Alzheimer’s disease, mood disorders, post-traumatic stress disorder). Our work focuses on learning-induced plasticity processes at different levels from the activity of neuronal networks (cerebral oscillations, synaptic plasticity, inhibitory networks), to cells (neurogenesis, morphology of neurons or glial cells, interactions between neurons and glia), neurobiological issues (protein or gene expression, release of neurotransmitters, role of mitochondria) to finally work at the molecular level (epigenetic regulations, role of transcriptional factors).
