Independent Component Analysis for Source Localization of EEG Sleep Spindle Components

Figure 4

Distributions of mean current source activity for part A (see Figure 1). In (a) sources are given for the original EEG. In (b) sources are given for the reconstructed EEG, representing the dominant spindle component (SC1) in this part. The reconstruction of the EEG was based on IC1. Each distribution is displayed relative to its own maximum, using three slices (axial, sagittal, and coronal) intersecting at the point of global maximum of the distribution. Current density values are in A/mm2.
