Fig. 2: Five brain regions whose resting-state functional connectivity (rsFC) with superior temporal gyrus (STG) were associated with 40 Hz auditory steady-state response (ASSR).

The five brain regions are shown in five sets of figures (A, D, G, J, M) on the left column and each region is shown by sagittal and axial views. A is from the left STG seed. The remaining D–M are from the right STG seed. A Left STG-seeded rsFC with right STG was significantly and positively linked to 40 Hz ASSR in the combined groups and within each group (B); and was significantly weaker in schizophrenia patients as compared with healthy individuals (C). D–O: Right STG-seeded rsFC with left temporoparietal junction (TPJ) (D), left medial prefrontal cortex (MPFC) (G), and left precentral gyrus (PrG) (J) also significantly predicted 40 Hz ASSR in both combined groups and within each group (E, H, K), and patients with schizophrenia showed significantly weaker rsFC (F, I, L). The only rsFC × ASSR interaction was found at right STG—right insula rsFC (M, N), but this rsFC was not significantly different between the two diagnostic groups (O). Seed region was written in italic. * FDR corrected p < 0.05 for five comparisons. n.s. non-significant. The left is shown on the left side of the MRI image.
