Independent Component Analysis for Source Localization of EEG Sleep Spindle Components

Figure 2

Independent Components (ICs) for the data in Figure 1. The exact IC values do not possess an interest, due to the sign and multiplicative constant indeterminacy of the results of ICA. The absolute maximum value of all ICs dictated a common magnitude range for the representation of the ICs. In each IC plot, the first (second) vertical dashed line indicates the time point of transition from part A (B) of the original single-spindle timeframe to part B (C).
