Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The broad aim of the study is to obtain a better understanding of alterations in mesolimbic reward pathways in adiposity based on the hypothesis of a hypofunctioning reward system in obesity.

This will be achieved by integrating a functional neuroimaging (fMRI) with behavioral reward tasks and the modulation of the dopamine level by dopamine depletion.
