Segmentation maps (4, 4). Segmentation of electrodes based on bicoherence at (4, 4): (a) for E01 and the left eye, (b) for E01 and the right eye, (c) for E02 and the left eye, (d) for E02 and the right eye. In each region, electrodes are linked to a representative electrode using lines whose thickness is indicative of the inverse of the BMAD value on a logarithmic scale. The thicker the line, the closer the two electrodes are in terms of their bicoherence fluctuation.
