Relationship between reward minus zero source accuracy and reward minus zero token difference scores in the (A) VTA/SN and (B) right parahippocampus. In controls, the correlation was significant in the VTA/SN and marginal in the right parahippocampus. In depressed participants, the correlation was not significant in either region. The strength of the correlations differed significantly between groups in the VTA/SN, with a marginal difference in the right parahippocampus.
