Research Theme

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. To understand how this activity is implicated in memorization and in informing ongoing behavior, we simultaneously record in downstream structures such as prefrontal cortex (affected in schizophrenia) and ventral striatum (affected in Parkinson's disease). This provides tractable experimental models for high-level cognitive representations at the level of single neurons and neural networks.
