A Brain synchrony analyses. Intra-brain and inter-brain phase synchronies in alpha band [0.5, 1] s. Links between electrodes means that the phase activities there are synchronized. All synchronies here were higher in FF groups than in FB groups (gray line). Blue line denotes the synchronies that were higher in CC epochs compared with DD epochs of FF groups (CC > DD) whereas red line denotes the synchronies that were higher in DD epochs compared with CC epochs of FF groups (CC < DD). Intra-brain synchronies are drawn in both brains and only one of each pair of inter-brain synchronies are drawn. Significant level was at p < 0.05, Bonferroni corrected. B Magnitudes of phase synchronies that showed significant strategical differences. These correspond to the links depicted as blue and red line in A. * p < 0.05; ** p < 0.01, Bonferroni corrected
