From: Impaired coupling of local and global functional feedbacks underlies abnormal synchronization and negative symptoms of schizophrenia

Figure 3

Spectral power and phase synchronization of beta and gamma bands. (A) Averaged power spectrum of normal (blue) and schizophrenia patients (red) group. Patients group exhibits reduced mean power above 25 Hz frequency range. (B) Bar plot of beta and gamma band power in normal and schizophrenia patients groups. Gamma band was significantly reduced in the patients group (p = 0.041). (C) Bar plot of beta and gamma band phase synchronization in the normal and schizophrenia patients groups. Beta band phase locking value (PLV) increased in the schizophrenia patients group (p = 0.0056). Bars and vertical lines indicate mean and standard errors, respectively. (D) Topological comparison of beta band phase locking value between two groups. Each edge represents significantly stronger beta band phase locking value than the other group based on p-value of 0.01 (Top) and 0.001 (Bottom).
