Table 4.

Changes in cross-correlation coefficient γx in electrode combinations in both (color—Grey) and (Grey—color) conditions; for n = 16. The bold ones (F3-F4, F7-F8, F3-F8, F4-F7, P3-P4, O1-O2, F3-F7, F4-F8) belong to the combinations representing homologous brain areas (Frontal, parietal and Occipital)

Average difference in γx in experimental conditions (color—Grey) and (Grey—color)
