Hyperexcitability of Cortical Oscillations in Patients with Somatoform Pain Disorder: A Resting-State EEG Study

Figure 4

Functional connectivity with the parietal region for resting-state alpha oscillations between patients and controls. The functional connectivity for resting-state alpha oscillatory activity was assessed using coherence between pairs of electrodes (a) and using lagged linear connectivity between pairs of cortical regions (b). Data are expressed using . ; n.s.: , independent-sample -test.
