FIGURE 14.4

(See Color Insert)Expected reward representations in vmPFC during action-based and stimulus-based decision making. (a) Illustration of action-based decision-making task in which subjects must choose between one of two different physical actions that yield monetary rewards with differing probabilities, and a stimulus-based decision-making task in which subjects must choose between one of two different fractal stimuli randomly assigned to either the left or right of the screen, which yield rewards with differing probabilities. (b) A region of vmPFC correlating with expected reward during both action- and stimulus-based decision making. (c) Time courses from vmPFC during the action- and stimulus-based decision-making tasks plotted as a function of model-predicted expected reward from low (blue) to high (red).
