Ventromedial prefrontal cortex lesions iowa gambling task

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

Functional anatomy of outcome evaluation during Iowa Gambling… In contrast, increased connectivity between these structures was observed after penalty in the control group. Our results suggest altered functioning of the basal ganglia and their connections with the cortical structures involved in the …

Ventromedial prefrontal cortex lesions were also associated with a deficit in processing gender specific social cues. One experiment tested the ability of patients with vmPFC lesions to categorize gender-specific names, attributes, and attitudes compared to patients with dorsolateral prefrontal cortex lesions and control subjects.

Performance on a widely used test of decision-making, the Iowa Gambling Task ( IGT), can discriminate controls from persons with ventral medial frontal lesions, ...
