Peters and Buchel206 have proposed that these areas can be viewed as distinct neural networks, based on the aspect of decision-making they are involved in: a valuation network - representing the subjective worth of discounted rewards - comprised of the ventromedial PFC, medial orbitofrontal cortex, ventral striatum, and posterior cingulate cortex; a cognitive control network - reflecting decision conflict and degree of exertion of cognitive control - comprised of the anterior cingulate cortex and lateral PFC; and a prospection network - reflecting prediction, affect, and prospection processes in decision-making and comprised of the medial temporal lobe (namely hippocampus and amygdala), with the ventromedial PFC and posterior cingulate cortex being involved in both valuation and prospection networks.
