A Three spectrograms (90-min duration) show the progressive improvement in signal quality for visual discrimination between SWS and REM (designated in the top hypnogram) between the raw EEG signal and the pruned EEG signal contaminating ICs removed, and the IC that maximally expressed brain activity. 1-min waveforms from SWS (B) and REM (C) show progressively improved signal quality from Raw EEG (purple), Pruned EEG (blue), and the ICs that maximally expressed brain activity (green)
