Altered Cognitive Function of Prefrontal Cortex During Error Feedback in Patients With Irritable Bowel Syndrome, Based on fMRI and Dynamic Causal Modeling
Open accessAbstract
Background & aims Patients with irritable bowel syndrome (IBS) have increased activity in the insula and reduced activation of the dorsolateral prefrontal cortex (DLPFC) in response to visceral stimulation. We investigated whether they have latent impairments in cognitive flexibility because of dysfunction in the DLPFC and insula and altered connectivity between brain regions.Methods We analyzed data from 30 individuals with IBS (15 men; age, 21.7 ± 3.0 y) diagnosed based on Rome III criteria, along with 30 individuals matched for age, sex, and education level (controls). Event-related functional magnetic resonance imaging of the brain was performed to evaluate cognitive flexibility and was assessed by the Wisconsin Card Sorting Test, in which subjects are allowed to change choice criteria, defined as set-shifting in response to error feedback. Brain images were analyzed with statistical parametric mapping 5 and 8 software and dynamic causal modeling.Results Subjects with IBS had significantly more Nelson perseverative errors (P < .05) and set-maintenance difficulties (P < .05) than controls. They also showed significantly decreased activity of the right DLPFC (Brodmann's area 9; P < .001) and right hippocampus (P < .001), and significantly increased activity of the left posterior insula (P < .001) at error feedback during set-shifting. Dynamic causal modeling analysis during set-shifting revealed significantly less connectivity from the DLPFC to pre-supplementary motor area in subjects with IBS, compared with controls (P = .012).Conclusions Individuals with IBS have latent impairments in cognitive flexibility as a result of altered activity of the DLPFC, insula, and hippocampus, and impaired connectivity between the DLPFC and pre-supplementary motor area.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
