(A) Topological distribution of phase–amplitude coupling (PAC) in the theta band (4–7 Hz), involving the phase component of postural fluctuations and band-specific EEG amplitude, for the control and SV conditions. (B) Scalp map of p values derived from paired t-tests, reflecting significant differences in ZMI between the control and SV conditions. (C) The contrast of pooled ZMI in the regions of interest (ROI), showing significant SV-related differences in theta PAC during stabilometer stance
