Over time, with more precision in their instruments, researchers showed that impairments confined to a specific region of the ventromedial prefrontal cortex?-the orbitofrontal cortex?-is especially likely to compromise performance on this … The neurological substrate of emotional and social intelligence Patients with lesions to the ventromedial (VM) prefrontal cortex have defective somatic markers and tend to exercise poor judgment in decision-making, which is especially manifested in the disadvantageous choices they typically make in … Effects of lesions of the nucleus accumbens core on choice… 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. c83lnp: Neuropsychology Visual Recognition: Inferior Temporal Cortex Mishkin & Pribham (1954).
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 ...
