Non-invasive imaging of propagating cortical rhythms

Abstract

Event Abstract Back to Event Non-invasive imaging of propagating cortical rhythms Gustavo Deco1* and Rikkert Hindriks1* 1 Universitat Pompeu Fabra, Department of Information and Communication Technologies, Spain Although cortical rhythms are known to play a fundamental role in perception and cognition, their spatiotemporal behavior is not well characterized yet, which hampers understanding of the involved mechanisms. The dominating view is that cortical rhythms are organized as functional networks in which spatially confined rhythms interact through white-matter pathways. In contrast, voltage sensitive dye imaging studies suggest that, at least on small spatial scales, cortical rhythms propagate and are organized as traveling waves. We argue that this view is appropriate also for large-scale rhythms as recorded with EEG and MEG and present data to illustrate this view. We propose improvements on existing methods for reconstructing the cortical currents underlying propagating rhythms as recorded with EEG and MEG, with particular focus on spatiotemporal regularization techniques. We compare the different methods through biophysical simulations.
