This project seeks to improve scientific knowledge of the decision-making processes of smokers and improve tobacco dependence treatments. The dorsolateral prefrontal cortex (DLPFC) influences decision-making by integrating inhibitory mechanisms with emotionally charged information from limbic regions, thereby exerting an inhibitory influence on seductive, immediately rewarding options with long-term costs, such as smoking. Delay discounting is the degree to which one de-values delayed outcomes, such as future health and long life. Converging evidence indicates that choosing a delayed option with a larger reward is associated with increased activity in the DLPFC. This study proposes that choosing to smoke after making a decision to quit reflects a situation where the DLPFC is insufficiently activated to exert an inhibitory influence on the immediately rewarding option of smoking.
