- Original description
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.Read full original descriptionShow less
Taste Physiology in Obese Volunteers Before and After Bariatric Surgery
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.
Inclusion: morbidly obese patients (BMI min 35kg/m2) scheduled for bariatric surgery; right handed.
Exclusion: cardiovascular disease; neurologic/psychiatric disorders.
