Degree centrality in REM-sleep group. The degree centrality (DC) values for awake, REM-sleep and N3-sleep states in SMA, SACC, LSMG, RSMG, and LMTG. (A) SACC: H(2) = 14.98, ${\eta }_H^2=0.41$, p < 0.001; post-hoc test showed N3-sleep < REM-sleep, p < 0.001, and N3-sleep < awake, p = 0.014. (B) SMA: H(2) = 14.01, ${\eta }_H^2=0.36$, p < 0.001; post-hoc test showed N3-sleep < REM-sleep, p = 0.001, and N3-sleep < awake, p = 0.003. (C) LSMG: H(2) = 6.94, ${\eta }_H^2=0.15$, p = 0.031; post-hoc test showed N3-sleep < REM-sleep, p = 0.014, and N3-sleep < awake, p = 0.085. (D) RSMG: H(2) = 8.53, ${\eta }_H^2=0.20$, p = 0.014; post-hoc test showed N3-sleep < REM-sleep, p = 0.007, and N3-sleep < awake, p = 0.089. (E) MTG:H(2) = 17.15, ${\eta }_H^2=0.46$, p < 0.001; post-hoc test showed N3-sleep < REM-sleep, p < 0.001, and N3-sleep < awake, p < 0.001. * means p < 0.05 FDR corrected.
