Altered PPI connectivity between the DLPFC and vACC in the BS group following surgery and correlation analysis between PPI connectivity and behavior measures. A. There was elevated PPI connectivity between the DLPFC and vACC when exposed to HC vs. LC food cues in Post-BS compared to Pre-BS group (PFWE<0.05). B. Prior to surgery, higher BMI was correlated with lower PPI connectivity between the right DLPFC and vACC. C. After the surgery, greater decreases in BMI were correlated with greater increases in PPI connectivity.

Abbreviation: Pre-BS, obese patients who received MRI scan before surgery; Post-BS, obese patients who received MRI scan at one month after surgery; DLPFC, dorsolateral prefrontal cortex; vACC, ventromedial anterior cingulate cortex; BMI, body mass index.
