Research in our lab focuses on the neural mechanisms of perceptual and cognitive functions. Current research in the lab aims to elucidate how spatial and feature attention modulates activity of single neurons and neuronal ensembles across a distributed network of cortical brain areas. We are particularly interested in the way the temporal structure of neuronal activity contributes to the formation of functional networks according to behavioral demands and its role in long-range communication among selected neuronal populations.
