Methods to characterize and interact with networks of the human brain.
Marzetti L., Pizzella V.
In the last decades, neuroscience has provided evidence for the dependence of human cognition and behavior on the formation of neuronal networks that link distributed brain regions. In this framework, physics applied to neuroscience significantly contributed to the development of technology as well as methods to characterize such neural networks from neuroimaging and electrophysiological data. In this talk, I will first present novel multidimensional methods to disclose brain network dynamics at temporal frequencies of behavior [1--100 Hz]. Emphasis will be put on linear and non-linear methods to characterize interactions occurring at the same frequency or at different frequencies, respectively. The second part of the talk will be devoted to presenting a novel multi locus transcranial magnetic stimulation device with two major characteristics: i) a spatial coverage that allows for stimulation of brain networks, other than single brain regions; ii) a stimulation with a flexible dynamics, based on real-time control signals from concurrent electroencephalography.
