(a) The posterior vmPFC showed a significant correlation between economic value and neural value. (b) A positive correlation (across subjects) between a neural value difference (defined as neural social value – neural monetary value) and the exchange rate between money and social values determined in behavior was found in the posterior vmPFC. A higher neurometric value difference was associated with a higher propensity to make an economic exchange. Adapted with permission from [36••]. (c) A subregion of the vmPFC/OFC showed a significant correlation between behavioral and neuronal rate of change. (d) A positive correlation (across subjects) was found between the ratio of money and food neural subjective values (marginal BOLD) in a subregion of the vmPFC/OFC with the ratio of the scaled marginal utilities of money and food measured behaviorally using a fitted exchanged rate between money and food. A higher neural ‘exchange rate’ was associated with a higher behavioral exchange rate. Adapted with permission from [37]. Each dot represents the value of one subject and the line represents the least square fit across subjects.
