Go - no go learning after frontal lobe lesions in humans.
48 patients with unilateral frontal or non-frontal cortical lesions were given a go - no go learning task. Patients with frontal lesions in either hemisphere took longer to learn the task and made more false "go" responses than control patients. They also, unlike controls, took longer to make in correct positive responses than correct positive ones. Medial frontal lesions were found to be particularly important in giving rise to poor performance on this task. It is suggested that this task is non-unitary in nature and that the medial area may be important for more than one ability.
