EEG statistical model. The 64-channel electrode array was divided into 3 rostrocaudal sections (anterior, central, and posterior) and sagittally into 3 additional sections (left, middle, and right) for a total of 9 distinct regions. Mean event-related potential (ERP) amplitude for conditions APE and APEVLead and each response, Suppressed or Not-Suppressed, was averaged over 5 electrodes (black circles) within each region. Representative electrodes plotted in subsequent figures are also labeled.
