Dichotic listening in crossed aphasia: "paradoxical" ipsilateral suppression.
In a 35-year-old right-handed man who had no personal or family history of left-handedness, left hemiparesis and predominantly motor aphasia suddenly developed following cerebrovascular accident. Clinical and laboratory data, including computerized tomographic scan, showed a clearly defined right hemisphere lesion. On dichotic listening test, a clear-cut right ear extinction was present.
