This study was concerned with the relationship between defects in sound recognition and intrahemispheric locus of lesion. Previous studies have shown that defects in sound recognition are common in association with left hemisphere lesions resulting in aphasias with comprehension deficits and are uncommon in association with other unilateral lesions. Current findings indicate that defects in sound recognition, occurring within the first month post onset of aphasia, may be associated with lesions of basal ganglia, the auditory cortex (both primary and association cortices), supramarginal gyrus, angular gyrus, and area 37. At the same time, however, a number of patients with lesions in these areas failed to show sound recognition defects.
