Figure 2.

Significant mean functional connectivity differences in the left fronto‐parietal network (FPN) between smokers and non‐smokers. A cluster within the left fronto‐insular cortex (FIC) was significantly more functionally coupled with the left FPN in all smokers than non‐smokers (green). The size and strength of this relationship increased when examining only the most severe smokers, that is, individuals with Faegerström scores ≥5, vs. non‐smokers (red). The degree of left FPN‐FIC integration significantly predicted discounting within the entire smoker group, but not within the non‐smoker group for both comparisons. Pearson's partial correlation coefficients indicate the strength of the association between group and discounting after controlling for age and education. NS = non‐smoker, S = smoker, SS = severe smoker. [Color figure can be viewed in the online issue, which is available at http://wileyonlinelibrary.com.]
