However, these specific task-based studies could not clearly uncover the alterations in the spontaneous brain networks that were associated with the general pain-related symptoms in PSPD.Patients and Methods: In the present study, 13 PSPD patients and 23 matched healthy controls (HCs) were enrolled. Resting state and 3D structural imaging data were collected during magnetic resonance imaging (MRI) scans. Ninety regions of interest (ROIs) were selected from the automated anatomical labeling (AAL) template. The functional connectivity toolbox “CONN” was used to calculate the functional connectivity (FC) coefficients.Results: Our results showed that PSPD patients exhibited increased FCs between the left thalamus and the right amygdala, the right hippocampus, and multiple sub-regions of the occipital lobe when compared to HCs. Correlation analysis revealed a negative correlation between the left thalamus-right amygdala FC and the level of anxiety in PSPD patients.Conclusion: These findings suggest that the altered FC between thalamus and amygdala may be the neural mechanisms underlying the pain-related anxiety in PSPD.Keywords: persistent somatoform pain disorder, functional magnetic resonance imaging, resting-state, functional connectivity  Sun XPan XNi KJi CWu JYan CLuo YDove Medical Pressarticlepersistent somatoform pain disorderfunctional magnetic resonance imagingresting-statefunctional connectivityNeurosciences.
