a Typical pulse profile of recorded-EEG (R-EEG) of dolphin when quiet (recording No. 2 in Table 1); b pulse profile of R-EEG that was a manually removed pulse of ECG from pulse of R-EEG in (a); c pulse of true-EEG (EEG) in which other artifact pulses were removed from the pulse of ECG-removed R-EEG in (b) by a band-pass filter; d the power spectrum resulting from frequency analysis of the EEG (c) by Fast Fourier Transform at recording positions hk in Fig. 1b
