Schematic overview of investigated CCMs. Interactions within EEG activity, within δ-EEG activity, as well as within α-EEG activity are examined at (A) ipsilateral vs. contralateral focus area positions, (B) ipsilateral near to focus area positions, and (C) ipsilateral far away from focus area positions for all children. Electrode positions are given for left-sided focus (note different locations for right-sided seizures in brackets).
