Regions in which gray matter volume was differentially correlated with gastrointestinal symptoms in patients with (A) ulcerative colitis and (B) irritable bowel syndrome compared to healthy controls, and (C) regions in which gray matter volume was differentially correlated with chronic stress in patients with irritable bowel syndrome compared to healthy controls (applying a significance level of p < 0.001, uncorrected for multiple comparisons). Axial slices are provided in Supplementary Figures 5–7. For details, see Tables 3, 4.
