Comparisons of left aINS/right aINS rs-FC between FCon and HS. (A) Resting-state functional connectivity based on the left anterior insula was compared between FCon patients and healthy subjects. (B): Resting-state functional connectivity based on the right anterior insula was compared between FCon patients and healthy subjects. Mask: 1= left insula; 2= right insula; 3 = left amygdala; 4 = right amygdala; 5 = anterior cingulate cortex; 6 = ventromedial prefrontal cortex. ** p <0.01. *p <0.05. aINS = anterior insula; L = left; pINS = posterior insula; PAC-SYM = patient assessment of constipation symptom questionnaire; R = right; rs-FC = resting-state functional connectivity.
