Graphic Representation of 10 Coherence Factor Loadings. EEG coherence factor loadings. Heads in top view, scalp left to image left; index electrode within heads and frequency range in Hz below. Region-Colors: Location, magnitude, and sign (red = positive; blue = negative) of maximally loading coherence on factor. Arrow-Colors: Direction of association indicated by arrow (red = increased coherence in CFS; yellow = decreased coherence in CFS).
