N2 - Obesity-related brain gray (GM) and white matter (WM) abnormalities have been reported in regions associated with food-intake control and cognitive-emotional regulation. Bariatric surgery (BS) is the most effective way to treat obesity and induce structural recovery of GM/WM density and WM integrity. It is unknown whether the surgery can promote structural changes in cortical morphometry along with weight-loss. Structural Magnetic Resonance Imaging and surface-based morphometry analysis were used to investigate BS-induced alterations of cortical morphometry in 22 obese participants who were tested before and one month post-BS, and in 21 obese controls (Ctr) without surgery who were tested twice (Baseline and One-month). Results showed that fasting plasma ghrelin, insulin, and leptin levels were significantly reduced post-BS (P < 0.001). Post-BS there were significant decreases in cortical thickness in the precuneus (PFDR < 0.05) that were associated with decreases in BMI. There were also significant increases post-BS in cortical thickness in middle (MFG) and superior (SFG) frontal gyri, superior temporal gyrus (STG), insula and ventral anterior cingulate cortex (vACC); and in cortical volume in left postcentral gyrus (PostCen) and vACC (PFDR < 0.05). Post-BS changes in SFG were associated with decreases in BMI. These findings suggest that structural changes in brain regions implicated in executive control and self-referential processing are associated with BS-induced weight-loss.
