Research statement

My research interests lie in the leading field of brain structure-function relationships and alterations in neuropathological conditions; the main aim is to relate neuroanatomical connectivity features to neurophysiological interactions and to identify modifications of these relationships in the NHP-model.

My studies in neuroanatomy are concerned with understanding inter-areal connectivity and brain networks’ basic characteristics. I use the chronic-ECoG technique and deep multi-laminar recordings to seek for neurophysiological correlates of hierarchical processing and cognitive integration during instrumental conditioning.
