Results of whole-brain contrast regional homogeneity (ReHo) maps acquired during near-threshold vs. no-tone condition.
Higher local connectivity in: (A) Right superior temporal gyrus (rSTG) in a sagittal (left), coronal (middle) and transversal (right) slice, as well as in (B) Anterior cingulate cortex (ACC) (p < 0.001, cluster-size corrected by means of Monte Carlo simulation, k > 22). (C) Higher local connectivity in right amygdala (rAmyg) when using a more lenient cluster threshold of k > 10.
