Associations between prefrontal responses during inhibition and ad libitum consumption. A, Greater vmPFC responses during reactive inhibition (Successful Stop vs Failed Stop) were negatively related to food consumption during the free-choice meal. For the contents of the meal and corresponding macronutrient information, see Extended Data Figure 6-1. B, Increased left superior frontal gyrus responses to greater Stop-signal probability were positively associated with food intake. Observations within the same participant are modeled with a line of best fit that reflects the overall brain–behavior association. While effects were derived from linear mixed-effects models, repeated-measures correlations were computed for visualization, using the rmcorr R package (Bakdash and Marusich, 2017).
