Iowa Gambling Task Impairment Is Not Specific To ... Prior research suggests that the Iowa Gambling task is performed poorly by individuals with lesions in the ventromedial prefrontal cortex (VMPFC). The current study investigated whether impaired performance in individuals with frontal lobe damage is determined by the existence of VMPFC lesions. A total of 14 participants with VMPFC lesions and 6 participants with frontal lesions not involving ... Contribution of different regions of the prefrontal cortex ... More precisely, our lesion analysis revealed that decision-making processes depend on a large cerebral network, including both ventromedial and dorsolateral areas of the prefrontal cortex. Consistent with past findings, our results support the claim that IGT deficit is not solitarily associated with ventromedial prefrontal cortex lesions.

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 ...

Animals must frequently make choices between alternative courses of action, seeking to maximize the benefit obtained. They must therefore evaluate the magnitude and the likelihood of the available outcomes.
