Figure 1 (A) Overview of ventral PCC (vPCC) cluster that is significantly more activated in normosensitive compared to hypersensitive FD patients during baseline (contrast Baselinenormo > Baselinehyper). (B) Overview and plot of contrast estimates from (Distension > Baseline)normo > (Distension > Baseline)hyper at the right anterior MCC (aMCC) local maximum, showing the deactivation during distension in hypersensitives, while no change is observed in normosensitives. (C) Overview and plot of contrast estimates from (Distension > Baseline)normo > (Distension > Baseline)hyper at the right Rolandic operculum local maximum, showing the deactivation during distension in hypersensitives, while activation is observed in normosensitives. Color bars represent t values. Gastroenterology 2010 139, 36-47DOI: (10.1053/j.gastro.2010.04.015) Copyright © 2010 Terms and Conditions
Figure 2 (A) Overview of hippocampus/amygdala cluster that is significantly more activated in patients without history of abuse compared to patients with history of abuse during baseline (contrast (Baselinenoabuse> Baselineabuse); 32.1% of the cluster is overlapping with the hippocampus, 21% with the amygdala. Color bar represents t values. (B) Plot of contrast estimates from (Distension > Baseline)abuse> (Distension > Baseline)noabuse at the right hippocampus/amygdala local maximum (Table 9), showing the lack of hippocampus/amygdala deactivation during distension in abused compared to nonabused patients.
