GEORGIA GREGORIOU

Dr Gregoriou holds a B.Sc. in Chemistry from the University of Athens and a M.Sc. in Neuroscience from the University of Crete. She did a PhD in Neuroscience at the Medical School of the University of Crete. Between 2001 and 2003 she worked as a postdoctoral fellow at the University of Parma in Italy. She then moved to the U.S.A where she worked as a postdoctoral researcher from 2003 to 2009 first at the laboratory of Neuropsychology at NIMH, NIH and then at the McGovern Institute for Brain Research at MIT In 2009 she moved to Greece where she currently holds an Associate Professor position at the Medical School of the University of Crete.

Research in Dr Gregoriou's 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. To this end, a multitude of techniques are employed including simultaneous multi-electrode extracellular recordings from multiple brain areas, permanent and reversible deactivation methods as well as electrical micro-stimulation methods.
