[Corpus callosum disconnection syndromes and functional organization or the corpus callosum in adults]

Knowledge concerning the role of the corpus callosum derives from the study of patients with lesions of spontaneous or surgical origin. Three major aspects are defined: interhemispheric elementary transfer of symmetrically organized messages, complex transfer of asymmetrically organized information, interhemispheric transfer and complex behaviors. Symptoms are both complex and rather limited; they can be missed if they are not specifically searched for.
