DISORDERS in perceiving and exploring the visual space contra-lateral to a brain lesion have been frequently escribed. Many patients with hemi-neglect for extrapersonal space also show neglect in a representational domain when the task requires imagining a well-known piazza from a given vantage point1,2 or comparing two visual images3-5. Cognitive6 and psychophysiological7 studies show a functional parallelism between the perceptual and imaginative domain7, indicating that spatial perception and imagery share the same neural substrata. Here we describe a patient with a persistent disorder in visual imagery for familiar piazzas in the absence of any neglect for stimuli located in a far8 or near 9 space or on his own body10. Contrary to previous cases involving imagery disorders, computerized tomography scans showed a lesion confined to the right frontal lobe, suggesting the role of the frontal lobe in some specific types of mental imagery. © 1993 Nature Publishing Group.
