Neuroimaging Data

Left: ventral striatal regions isolated by regression of monetary values against BOLD responses to cue display. Right: visual cortical regions isolated by correlation of cue-value regression coefficients with individual payoffs. Slices were taken at global maxima of interest indicated by red pointers on the above axial glass brains. Areas shown in gray/black on glass brains and in orange/yellow on coronal slices showed significant effect. The [x y z] coordinates of the maxima refer to the Montreal Neurological Institute space.

(A) Statistical parametric maps using conservative threshold (p < 0.05 after familywise error correction for multiple comparisons).

(B) Statistical parametric maps using liberal threshold (p < 0.001 uncorrected).

(C) Regression coefficients of Q values (QV) and prediction errors (PE) against BOLD responses to cue and outcome display, respectively. Bars are ± intersubjects standard errors of the mean.
