Fig. 5: Cross-frequency modulation of phase synchronization between hippocampus and neocortex.
From: Phase-based coordination of hippocampal and neocortical oscillations during human sleep
Normalized modulation indices (MIZ) for phase of HPC (a) and NC (b). White outlines indicate clusters of significantly greater than zero modulation across patients (cluster-based permutation test). c Comparisons of HPC- and NC-phase-dependent modulation of phase synchronization for each SO-based cluster. *P < 0.05, **P < 0.01, ***P < 0.001 (Wilcoxon signed rank test, uncorrected). N = 8 for N3, N = 10 for N2 and REM.
