Abstract
A 33-year-old right-handed man with intermittent headache was found to have agenesis of the corpus callosum. He underwent magnetic resonance imaging, positron emission tomography (PET), and detailed neuropsycho logic tests, including a Wada test. There was bilateral representation of language, and a PET activation study with word repetition revealed bilateral areas of activation that were not completely symmetric. The se findings and the literature concerning agenesis of the corpus callo sum are discussed as is the possible compensatory mechanism for absenc e of the corpus callosum, which is important for cross-communication.
