The ventromedial prefrontal cortex (vmPFC) and insular cortex are implicated in distributed neural circuitry that supports emotional decision-making. Previous studies of patients with vmPFC lesions have focused primarily on decision-making under uncertainty, when outcome probabilities are ambiguous (e.g. the Iowa Gambling Task).

Relationships between executive function, working memory, and decision‐making on the Iowa Gambling Task: Evidence from ventromedial patients, dorsolateral patients, and normal subjects Examining Theories of Ventromedial Prefrontal Cortex Function ... The ventromedial prefrontal cortex (VMPFC) is an intriguing brain region which sends output to and receives input from memory, emotion and reward related structures such as the amygdala, hippocampus, and caudate nucleus. Humans with lesions to the VMPFC on the surface seem to function normally and most have normal intelligence. Different Contributions of the Human Amygdala and ... Abstract. The somatic marker hypothesis proposes that decision-making is a process that depends on emotion. Studies have shown that damage of the ventromedial prefrontal (VMF) cortex precludes the ability to use somatic (emotional) signals that are necessary for guiding decisions in the advantageous direction. The cognitive and behavioral effects of meningioma lesions ...

popular paradigm has been the Iowa Gambling Task (IGT) (Bechara, Tranel, & Damasio, 2000). The IGT was originally designed to elucidate some of the particular deficits found in patients with bilateral ventromedial prefrontal cortex lesions (VMF). The IGT is a reinforcement learning problem, in that participants must learn from rewards and ...

Waters-Wood, Lin Xiao, Natalie L. Denburg, Michael Hernandez, Antoine Bechara Iowa Gambling Task - an overview | ScienceDirect Topics Lesions of the human ventromedial prefrontal cortex (VMPC) have been shown to impair normal emotional responses and to decrease emotional intelligence. 2. Human VMPC lesions are associated with decision-making deficits in real life and on the Iowa Gambling Task (IGT), a laboratory model of real-world decision-making. 3.
