Two groups of subjects will be constitute: (i) patients with circumscribed brain injury (including stroke, vascular malformations, tumor or circumscribed infectious lesions) or degenerative/developmental disorders and selective cognitive disorders; (ii) healthy control subjects. The objective of this project is to evaluate specific neuropsychological deficits and apply current brain imaging techniques (anatomical, diffusion, functional, magnetic stimulation) to patients suffering from these cognitive deficits due to brain damage, in order to elucidate the brain mechanisms underlying these deficits.
