Cerebral effects of glucagon‐like peptide‐1 receptor blockade before and after Roux‐en‐Y gastric bypass surgery in obese women: A proof‐of‐concept resting‐state functional MRI study

To assess the effects of Roux-en-Y gastric bypass surgery (RYGB)-related changes in glucagon-like peptide-1 (GLP-1) on cerebral resting-state functioning in obese women.In nine obese females aged 40-54 years in the fasted state, we studied the effects of RYGB and GLP-1 on five a priori selected networks implicated in food- and reward-related processes as well as environment monitoring (default mode, right frontoparietal, basal ganglia,...
