EEG, EMG signals at burst-suppression level under propofol anaesthesia. (a) Typical example of EEG (Fp1–M1) signal with overlying single motor unit potential (upper panel) and its EEG power spectrum (lower panel). This signal has peaks at 6.6 Hz and harmonic frequencies. (b) Submental muscle activity (upper panel) and its EMG power spectrum (lower panel). Power spectrum shows peaks at the firing frequencies of motor units and as a joint effect, the power spectrum reaches down to 0 Hz.
