Study Summary
The purpose of this research study is to better understand why people gain weight when they quit smoking by examining food intake and changes in brain activity in smokers when they are smoking as usual compared to when they have been deprived of cigarettes (i.e., have not smoked for 4 days) as compared to a non-smoker control group.
Primary Outcome
The primary outcome measure is change in BOLD signal for the Food Cue-Induced Craving primary regions of interest for the BOLD fMRI analysis are anterior cingulate gyrus (ACC), Insula, Ventral Striatum (VS), and orbital frontal cortex (OFC). For the Working Memory N-Back Task the primary regions of interest for the BOLD analysis will be dorsal lateral prefrontal cortex (DLPFC) and posterior cingulate gyrus (PCC).
