title: The neural basis of anosognosia for spatial neglect after stroke.
abstract: OBJECTIVE
  The present study investigated the lesion anatomy of anosognosia for visuospatial neglect resulting from right hemispheric stroke.
  
  
  METHODS
  In 63 patients, self-ratings of performance in paper-and-pencil tests were contrasted with external performance ratings. Lesion analysis was conducted on patient subgroups with different degrees of anosognosia but comparable visuospatial impairment.
  
  
  RESULTS
  Independent of the severity of visuospatial neglect per se, damage to the right angular and superior temporal gyrus was associated with higher levels of anosognosia.
  
  
  CONCLUSIONS
  Using a novel assessment of anosognosia for spatial neglect, the present study relates stroke-induced self-awareness deficits to inferior parietal and superior temporal brain damage.
