Insensitivity to future consequences following damage to human prefrontal cortex
Deciding Advantageously Before Knowing the Advantageous Strategy
The results suggest that, in normal individuals, nonconscious biases guide behavior before conscious knowledge does, and without the help of such biases, overt knowledge may be insufficient to ensure advantageous behavior.

Here I argue that addicted people become unable to make drug-use choices on the basis of long-term outcome, and I propose a neural framework that explains this myopia for future consequences. I…
Characterization of the decision-making deficit of patients with ventromedial prefrontal cortex lesions.
Patients with VM lesions are insensitive to future consequences, positive or negative, and are primarily guided by immediate prospects, according to this study's designs of a variant of the original gambling task.
Emotion, decision making and the orbitofrontal cortex.
The somatic marker hypothesis provides a systems-level neuroanatomical and cognitive framework for decisionMaking and the influence on it by emotion and the relationship between emotion, decision making and other cognitive functions of the frontal lobe, namely working memory is reviewed.

The results suggest that amygdala damage is associated with impairment in decision-making and that the roles played by the amygdala and VMF in decision -making are different.
Subcortical and cortical brain activity during the feeling of self-generated emotions
The hypothesis that the process of feeling emotions requires the participation of brain regions that are involved in the mapping and/or regulation of internal organism states is tested, indicating the close relationship between emotion and homeostasis.
