Auditory neglect and right parietal cortex
Neuropsychology Unit, University Department of Clinical Neurology, Radcliffe Infirmary, Oxford, UK
Many patients who have suffered right hemisphere stroke seem initially unresponsive to voices and environmental noises that emanate from their left (Heilman and Valenstein, 1972
). The question of whether more subtle deficits might persist post-acutely, and whether, like visuospatial neglect, they really are more common after right than left hemisphere damage, has been comparatively little studied. Until fairly recently, auditory neglect was the poor relation of visual neglect.
In part, this is because there are no auditory analogues of simple search tasks such as target cancellation, or of drawing or copying. Auditory bisection performance, where the subject is required to point to a position in space midway between two sound sources, has been reported (Ruff et al., 1981): patients
