Some Computational Aspects of the Brain Computer Interfaces Based on Inner Music
Figure 4
Left side: spectrograms with 800 power spectra parts (frequency interval 500–550 Hz) of two EEG channels with the inner tone c2, lower and middle; their dot product-left top-top view and the side view on the right side-giving the enhanced c2 in the composite spectrogram, well discernible. Time duration 5 seconds.
