Top illustrates an example of 5-hour raw EEG tracings recorded with a 256-Hz sampling frequency. Middle shows 3 aEEG tracings obtained using M1 (red), M2 (black), and M3 (green). Last shows two highlighted sections of 5-minute each, segmented from the same aEEG tracing derived from M1(red), M2 (black), and M3 (green), respectively.
