Patients with left-sided neglect following a right hemisphere lesion, fail to report, orient to, or verbally describe stimuli in the contralesional left hemispace. Similar observations are made in the representational domain. When asked to describe a familiar scene from a mental image, many of those patients also omit details of what would have been on their left. Although right-sided neglect after left brain damage has been observed in patients previously, right-sided representational neglect (henceforth RN) on traditional RN tasks has not yet been described in the literature. Here we describe a patient who suffers from right-sided RN in scene description and in tasks requiring the mental representation of objects. Further neuropsychological investigations showed a preserved visuo-spatial working memory capacity for maintaining locations on either side of space. The results are discussed in the light of recent insights into the neglect syndrome.
