Abstract
Unilateral spatial neglect (USN) is commonly observed following right hemisphere injury. Many authors suggest this is because the right hemisphere constructs the network of spatial attention. Recently, prism adaptation (PA) has been reported as a remarkable approach for USN to reconstruct space representation. In this study, a patient with right brain injury with crossed aphasia and USN showed improvement of USN following PA. Crossed aphasia refers to aphasia occuring after right brain damage in right-handers and is recognized as atypical cerebral dominance. The present results suggest that the function of spatial representation was located in the right brain of this patient and redundancy of each cortical function might have been occurring at the individual level. So we need to take care in choosing therapeutic approaches for cases with anomalous dominance.
