Plain English: We observed individual differences in a value-directed remembering task. White matter integrity within the Uncinate Fasciculus correlated with memory strength for high-value items. This relationship was also seen for the tract connecting the Nucleus Accumbens (NAcc) and Ventral Tegmental Area (VTA). Additionally, structural integrity of the NAcc –> VTA tract correlated with the degree an individual was selective about the information they retained (i.e. preferential recall for high-value over low-value items).
