EEG regions and sub-regions. Overview of the ten defined EEG sub-regions, related abbreviations, and EEG channels. CPz was set as reference electrode and, therefore, is missing here. For statistical purposes, the coherence parameters (see below) of sub-regions were again averaged, which led to three regions: EEG central (EEGcen), EEG left (EEGle), and EEG right (EEGri) (see statistics).
