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. Brain Characterization of the decision-making deficit of ...

Sex differences in the functional lateralization of emotion ... THE VENTROMEDIAL PREFRONTAL CORTEX. Decades of research on the ventromedial prefrontal cortex (vmPFC) have identified it as a neurological structure critical to decision making, emotion regulation, and social functioning (Eslinger and Damasio, 1985; Bechara et al., 1994; Damasio et al., 1994). Lesions to the vmPFC can impair individuals ... Lesion mapping of cognitive control and value-based decision ... Iowa Gambling Task; The prefrontal cortex (PFC) is widely regarded as the pinnacle of brain evolution in humans . Its functional organization has long been under scientific scrutiny and has often been subsumed under the rubric “executive functions” (1, 2).
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).
Executive functions include basic cognitive processes such as attentional control, cognitive inhibition, inhibitory control, working memory, and cognitive flexibility. Dissociation Of Working Memory from Decision Making within the… We tested the hypothesis that cognitive functions related to working memory (assessed with delay tasks) are distinct from those related to decision making (assessed with a gambling task), and that working memory and decision making depend … Comparison of the Effects of Bilateral Orbital Prefrontal… The present study examines the effects of bilateral orbital prefrontal cortex (PFo) lesions on monkeys' emotional responses in two different contexts: in the presence of a rubber snake and in the presence of a human intruder. Irrational Economic Decision-Making after Ventromedial…
