The research objectives are addressed using a unique combination of invasive, intracranial EEG recordings with laminar resolution in humans to investigate local mechanisms, and whole-brain magnetoencephalographic recordings and cutting-edge functional connectivity analysis to identify brain areas as sources and/or targets of predictions, thus relating local to global mechanisms.
Magnetoencephalographic (MEG) studies also have used graph theoretical methods.
11) Results of a study examining magnetoencephalographic (MEG) signals on visual-feature matching tasks in TBI patients versus healthy controls revealed an increase in gamma synchronization in the visual cortex of TBI patients, which authors propose "reflect the extra effort that the patients used to compensate for inefficient sensory processing due to disruption of cortical network by their injury".
