Schematic depicting the calculation of functional connectivity from cEEG. Top: An example of 11 s of cEEG data from a patient undergoing an anaesthetic wean. Middle: Two pairs of 1-s long EEG tracings are highlighted. The cross correlations between pairs are shown. Bottom: Two examples of the functional connectivity maps are shown, with circles (the ‘nodes’ of the functional connectivity maps) representing each EEG lead and lines (the ‘edges’ of the functional connectivity maps) representing connections defined by a statistically significant peak in the cross-correlogram between the signals recorded from each lead.
