    Abstract

    A patient with left visuo-spatial neglect after right fronto-parietal haemorrhage failed to cross out stimuli in left space on cancellation tests. Her bisections of horizontal lines were displaced significantly to the right of true centre. On drawing and copying tasks, she sometimes omitted features on the left (neglect) and sometimes transposed them to right space (allochiria). This co-occurrence of neglect and allochiria has been observed previously but has provoked little theoretical comment. We draw attention to aspects of the combination that seem critical to the interpretation of visuo-spatial neglect.
