The ventromedial prefrontal cortex (VMPFC) have been implied in emotional decision making, because it seems to have a role in affective reversal learning, risk proneness, and impulsive behaviour. The variety of connections of the VMPFC with several cortical and subcortical areas, as the amygdala, make likely that it can play a significant function in the control y regulation of human behaviour. In this work we reviewed studies on the Iowa Gambling task, the affective reversal learning task, lottery tasks designed to measure risk propensity, and reward delayed tasks designed to measure impulsivity. These tasks have been applied to VMPFC patients, patients with damages in other prefrontal areas, and controls. The patterns of behavioural y brain activity data can be best accounted for assuming that the VMPFC build up a representation of the expectation of reinforcement. Reinforcement amount, delay, and variance are integral parts of the representation of an expected reinforcement. [ABSTRACT FROM AUTHOR]
