The brain structure and function are naturally modelled as networks with cytoarchitectonic areas and deep brain nuclei represented as nodes and the white matter or some measure of functional connectivity as edges in a graph. This project will add to the increasingly popular network model of the brain the coupling to the global electrical current flow generated by the collective neuronal activity. This model will be tested using Magnetoencephalography (MEG) and electroencephalography (EEG) data. The ESR will test two hypotheses:
- passive flow of electrical current interacts with the processing based on the network of white matter connections
- this interaction has consequences for normal activity in awake state and sleep and possibly in pathology. The transferability of connectivity techniques and ideas will utilise results of other projects where the interaction between global flow and network activity is evident, e.g. ecogeomorphology of dryland and/or fluvial environments.
