Figure 1From: A methodology for time-frequency image processing applied to the classification of non-stationary multichannel signals using instantaneous frequency descriptors with application to newborn EEG signalsEEG scalp sensor electrodes (from [3]): (a) Lateral view of the electrode positions in a realistic display. (b) Electrode position and labels for various systems. Black circles indicate positions of the original 10-20 system, gray circles indicate additional positions in the 10-10 extension and small dots indicate additional positions in the 10-5 extension [3].Back to article page
