    <mods:abstract>Irritable bowel syndrome (IBS) is a chronic pain disorder characterized by
        chronic altered bowel activity with no known organic cause, resistance to any one form of
        treatment and heterogeneity in experiences of symptoms. Our previous study used behavioral
        measures of somatization and resting state fMRI data from 26 female adult patients with IBS
        and found evidence suggesting that somatization behavioral measures correlate with
        functional connectivity of insula to the anterior cingulate cortex (ACC). We now attempt to
        extend these earlier findings to analyze, through a graph theory perspective, what network
        properties characterize the insula and ACC in high somatizers compared to low somatizers.
        Using CONN Toolbox v15, we found high node degree in the anterior insular cortex (AIC) in
        both groups of somatizers, but only low somatizers showed high node degree in the posterior
        insular cortex (PIC) when we analyzed the AIC, PIC and ACC. A high node degree indicates the
        crucial role of a node in information integration in a network, and our results suggests the
        existence of the PIC as a potential hub to be a defining feature characterizing low
        somatizers.</mods:abstract>
