Study Overview
Brief Summary
The objective is to investigate neuro-anatomical correlates of gastrointestinal taste stimulation by means of functional MRI before and after bariatric surgery. Intragastric administration of glucose, monosodium glutamate, chloroquine and placebo is followed by functional brain MRI in obese humans before and 3 months after surgery.
