Orbitofrontal cortex encodes the subjective value of food rewards in humans. (a) Hungry subjects bid on snack foods, which were the only items they could eat for 30 minutes after the experiment. At the time of the decision, medial orbitofrontal cortex (b) tracked the subjective value that subjects placed on each food item. Activity here increased as the subjects willingness-to-pay for the item increased (c). Reprinted with permission from Plassmann et al. (2007).
