Brief Summary:
Electroencephalography EEG with very high spatial resolution HR-EEG 256 electrodes allow for better analysis of local and global activity of the cerebral cortex as compared with conventional EEG Since January 2012 the Neurology Department of CHU Rennes is the first clinical service in France equipped with such a system
Applied to HR-EEG recordings brain connectivity methods are likely to provide essential information in the form of connectivity graphs on cortical networks either dysfunctional or not involved in the generation of interictal paroxysms like spikes or spike-waves and during seizures
So far many methods have been proposed see for a review Wendling et al 2009 Wendling et al 2010 However since each method is highly sensitive to the type of model that is assumed for the underlying relationship between distinct brain regions Ansari-Asl et al 2006 none of them has yet demonstrated its effectiveness
