Figure 1: Comparisons of resting-state EEG oscillations for patients and controls. Grand average resting-state spectral power density (measured at parietal electrodes (a)) in the frequency range of 1-45 Hz for SPD patients (orange line) and healthy controls (green line). Within the frequency interval 8.5-12.5 Hz (marked using a grey rectangle), patients exhibited significantly greater spectral power density than healthy controls ( value, vertical red line (b); ; 5,000 permutations).
