Small world brain network characteristics during EEG Holter recording of a stroke event

Several studies revealed that cerebral ischemia provokes transient or permanent disruption of functional connections both locally and distantly from the lesion. Recently, brain connectivity has been described using graph theory, a mathematical approach which depicts the brain as a network in order to simplify its complex topology. The human brain consists of complex inhibitory and excitatory circuits located in specialized areas, which are engaged in sharing and integrating information with a time-varying interplay at resolution in the millisecond range.
