Electrophysiological and neuroimaging approaches for the investigation of functional brain networks

Despite the continuous advances in brain imaging and signaling techniques, our knowledge of the human brain remains incomplete. In the study of the fascinating yet complex brain connectome, only the integration of complementary techniques can provide a more complete view and extend the spatio-temporal domain coverage. Likely, multiple analytical frameworks are required to comprehensively unravel the brain’s interaction patterns. The aim of this talk is to provide an overview of the areas of integration of neuroimaging and electrophysiological techniques and processing pipelines that are relevant for the study of functional brain networks. We will describe the principles, advantages, and drawbacks of techniques such as functional magnetic resonance imaging (fMRI) and electroencephalography (EEG), as well as unimodal and multimodal analysis approaches for the study of functional brain networks. Finally, we will present exemplary applications of these approaches in the study of neuropsychiatric disorders for which a dysconnectivity hypothesis has been proposed.
