The main goal of our group is to determine whether and how astrocytes play an active and direct role in information processing. We want to unravel the molecular modalities and functional outcomes of neuroglial interactions in physiological and pathological conditions. More precisely, we want to understand how neurons and glia communicate in various regimes of activity and determine the outcome of disrupting their communication on neuronal functions, including their excitability, synaptic transmission, plasticity and synchronization.
Our research targets the neurophysiological basis of spatial navigation and memory, in particular the network processes that integrate internal signals (representations, expectations, emotions) and multisensory information from the environment to store and update memories, and guide behavior. We record large neuronal ensembles and local field potential oscillations in freely moving animals performing learning and memory tasks. We focus on the hippocampal system (affected in epilepsy and Alzheimer's disease), where neurons code for the position and direction of the head in space.
