Figure 3: Relationship between somatization severity and resting-state alpha oscillation in SPD patients. After accounting for the influence of anxiety and depression, the residual somatization severity was significantly correlated with residual alpha oscillation power density at parietal electrodes and marginally significantly correlated with the residual eLORETA cortical current density at the parietal lobe. Each grey dot represents values from a single SPD patient, and black lines represent the best linear fit.
