The wavelet spectrogram and the sLORETA sources of sleep. The spectrogram (left) has seconds in horizontal axis, whereas the 0 value represent the point of auditory stimulation. The vertical axis denotes the frequency increasing towards bottom (Hz). The possible sources are presented at right side with a sLORETA power maxima matching the 100 ms (N1).
