Results from between-group analyses of FC in hypersensitive compared to normosensitive IBS patients within the salience and sensorimotor networks by two sample t-tests. Only results of region-of-interest analyses at p_FWE-corrected < 0.05 are shown and exact unilateral p-values are given for peak voxel analyses. H = hemisphere; ACC = anterior cingulate cortex.
