Neglect is most commonly observed and studied in the horizontal spatial dimension. Vertical neglect has been described in a few studies. We now report on a patient with near radial space neglect following bilateral posterior parietal lobe lesions. Our patient also had neglect of inferior vertical and left horizontal space. These spatial deficits appear primarily attentional. Our findings compliment other studies that demonstrate neglect may occur in multiple spatial dimensions and provide evidence for a three-dimensional attentional system in humans. Whereas neglect of inferior vertical space may be associated with bilateral parietal lobe lesions, neglect of superior vertical and far radial space has been associated with bilateral inferior temporo-occipital lesions.
