The present research project aims to study the effects of bariatric surgery and liraglutide administration (in patients already selected for one of these procedures) on two cognitive-behavioral processes partially supported by distinct brain networks: automatic approach tendencies (underpinned by the cue-reactivity network) and behavioral inhibition (underpinned by the cue-regulation network). Additionally, the investigators aim to study how these processes may be modulated by satiety. The secondary objective of the project includes identifying cognitive-behavioral markers that can predict the response to these treatments.
