Our Research

The project investigates the role of spontaneous activity in the vmPFC and in its mesocortical dopaminergic inputs in the consolidation of fear extinction memories. Resting-state fMRI is used both in rodents and in humans. Physiological insights obtained from combining fMRI with Calcium recordings and optogenetics in rodents will deepen our understanding of neurobiological mechanisms in humans; advanced multivoxel analysis methods in humans, in turn, will guide and inform the analysis of fMRI and Calcium recording data in the rodent.
