Figure 1

Scalp maps and dipole source locations of six independent component clusters across twenty-four subjects. Left panel: Individual scalp maps indicate components found by ICA for a single subject. Middle panel: Mean scalp maps averaged across components within a cluster. Right panel: Plot of 3D dipole source locations and their projections onto the MNI brain template. (A) lateral occipital (n = 16, s = 11), (B) right sensorimotor (n = 16, s = 16), (C) left sensorimotor (n = 16, s = 15), (D) medial parietal (n = 12, s = 12), (E) medial frontal (n = 11, s = 11), and (F) superior parietal (n = 10, s = 9) (representing the number of components n contributed by the number of subjects s within a cluster).
