The aim of this article was to review the different levels of interaction between motivation and decision-making under uncertainty, based on the Iowa Gambling Task, with specific attention to their neuronal structures. The influence of motivation has been observed on many cognitive functions, and its influence appears to be important on the decision-making process under uncertainty. However, few studies treat this influence. Several structures have been found to be implied in both motivational and decision making processes. The anterior cingulate cortex is an essential interface between motivation and executive functions. In addition, the activity in the ventral striatum is correlated with motivation while this region is under the influence of somatic markers. The interaction of both structures leads to an anticipation of future outcomes. The ventromedial prefrontal cortex is under the influence of the motivational states that potentiates the somatic markers effect on the directional and activational aspect of behaviors. In this review we were able to show that the level of uncertainty and the degree of motivation are two factors that influence action selection and that this interaction is visible from a behavioral and neuronal point of view.
