Dynamics of resting brain fluctuations — •Vesna Vuksanovic1,2 and Philipp Hövel1,21Technische Universität Berlin, Germany — 2Bernstein Center for Computational Neuroscience Berlin, Germany

Despite important progress over the last few years, brain functional connectivity at rest ``i.e.'' under no stimulation and in the absence of any overt-directed behaviour, is still not well understood. In studies on goal-directed mental activity, spontaneous brain activity at rest has been considered as random enough to be averaged out across many trials. However, well organized spatio-temporal low-frequency fluctuations (<0.1 Hz) have been observed in blood-oxygen-level-dependent (BOLD) fMRI signal of human subjects during rest. These well organized patterns of activity, suggest the existence of underlying dynamics that governs intrinsic brain processes. Here, we address resting brain fluctuations in fMRI data proposing some possible routes of studying the underlying dynamics.
