Neuroimaging results. A–C, BOLD signal increases for the Imagine versus the Estimate task (A), the parametric modulation by reward magnitude in the Imagine versus Estimate task (B), and the conjunction of both contrasts (C). (For display purposes, the SPM is thresholded at p < 0.001, uncorrected, at least 10 contiguous voxels.) D, E, Parameter estimates, averaged from a 5 mm sphere centered on the peak of the conjunction contrast, for the task effect (D) and the parametric modulation of the Imagine task by reward magnitude (E). Connected blue diamonds indicate the mean-centered natural logarithm of the reward magnitudes. Error bars reflect the SEM.
