Perceiving left and imagining right: dissociation in neglect

Signor Piazza, a patient with a left parieto-occipital haemorrhage and a ri ght thalamic stroke, showed severe right personal neglect (e.g. touching ow n body parts) and right perceptual neglect in tasks with (e.g. cancelling t asks) or without (e.g. description of a complex picture) motor response. He had also right-sided neglect dyslexia (including single words), without la nguage impairments. However, the patient also presented with a clear left-s ided deficit in the representational domain (e.g. imagery tasks). Signor Pi azza's pattern of performance suggests dissociation between imagery and per ception within the neglect syndrome.
