Obesity, Abnormal ‘Reward Circuitry’ In Brain Linked By Imaging Studies

Using brain imaging and chocolate milkshakes, scientists have found that women with weakened “reward circuitry” in their brains are at increased risk of weight gain over time and potential obesity. The risk increases even more for women who also have a gene associated with compromised dopamine signaling in the brain. The results, drawn from two studies using functional magnetic resonance imaging (fMRI) at the University of Oregon’s Lewis Center for Neuroimaging, appear in the Oct.
