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 ... Dissociation Of Working Memory from Decision Making within ... Normal controls ( n = 21), subjects with lesions in the ventromedial (VM) ( n = 9) or dorsolateral/high mesial (DL/M) prefrontal cortices ( n = 10), performed on (1) modified delay tasks that assess working memory and (2) a gambling task designed to measure decision making. Ventromedial prefrontal cortex - WikiVisually The ventromedial prefrontal cortex (vmPFC) is a part of the prefrontal cortex in the mammalian brain.The ventral medial prefrontal is located in the frontal lobe at the bottom of the cerebral hemispheres and is implicated in the processing of risk and fear.

In a related line of research, the Iowa Gambling Task (IGT) was developed to test the performance of vmPFC patients on a laboratory ... Human lesion studies of ventromedial prefrontal cortex ... Iowa gambling task - Wikipedia The Iowa gambling task (IGT) is a psychological task thought to simulate real-life decision ... By contrast, patients with amygdala lesions never develop this physiological ... In another test, patients with ventromedial prefrontal cortex ( vmPFC) ... The Iowa Gambling Task in fMRI Images - NCBI The Iowa Gambling Task (IGT) is a sensitive test for the detection of ... Specifically , a neural circuitry involving the dorsolateral prefrontal cortex (for working memory), ... Neurological patients with damage to the mesial orbitofrontal/ ventromedial ... Iowa Gambling task impairment is not specific to ventromedial ... - NCBI
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 ...

PDF | 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 ... 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.

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. The amygdala and decision making - PubMed Central (PMC) Decision-making is a complex process that requires the orchestration of multiple neural systems. For example, decision-making is believed to involve areas of the brain involved in emotion (e.g., amygdala, ventromedial prefrontal cortex) and memory (e.g., hippocampus, dorsolateral prefrontal cortex).
