title: Topographical heading disorientation: a case study.
abstract: We report the case of a patient with selective topographic orientation deficits in both familiar and novel environments after bilateral medial occipital infarctions. Extensive neuropsychological assessment revealed intact functioning in all other cognitive domains. The findings are interpreted in terms of a dissociation between the retrosplenial posterior cingulate and the superior parietal lobule in the right hemisphere.
