Full Brain Network Dynamics - modeling, analyses, experiments

Over the last ten years the information on large scale connectivity composed of the white matter fibers, called the Connectome, has become widely available and lead to many new investigations regarding the theory and modelling, as well as analyses and experimentation of full brain networks.

Such brain networks pose novel challenges to theory and computation, since their architecture poses novel constraints upon neuroinformatics platforms (see for instance thevirtualbrain.org).

In particular, they are characterized by a complex connectivity matrix, time delays via signal propagation along their many connecting fibers with neural mass models at their network nodes.

Even at rest, the full brain networks do not dwell at equilibrium, but show a rich spontaneous dynamics with intermittent coherent fluctuations and characteristic spatial patterns.

These spatiotemporal dynamics and its associated cognitive processes are perturbed during brain diseases and disorders such as schizophrenia, autism and epilepsy.

For these reasons the resting state dynamics offers itself as an exciting entry point to the study of cognition through the investigation of their associated brain processes in full brain networks.

In this workshop we gather researchers and experts in the field discussing the various aspects and challenges related to full brain network dynamics from diverse perspectives including theory and experiments.

Each speaker has been allotted a time slot of 45 minutes (30 minutes presentation and 15 minutes discussion), which allows ample time for discussion.
