Impact of Bariatric Surgery and Liraglutide on Cognitive-Behavioral Markers of Long-Term Weight Loss in Obesity

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.
