Increased activity for imagined juice rewards in vmPFC is associated with greater frequency of choosing to wait for larger, later monetary rewards. a, The white circle outlines the 10-mm sphere in vmPFC from which BOLD data were extracted for all analyses described in Results. b, The scatter plot illustrates the relationship between the contrast for imagining versus consuming juice in the vmPFC ROI and the percentage of trials where a participant chose to wait for the larger, later monetary reward. Each black dot represents one participant. The dashed gray line indicates the best linear fit to the data.
