Rotated drawing: The range of performance and anatomical correlates in a series of 16 patients

Recently there has been interest in an unusual neuropsychological disorder in which the patient copies a complex drawing in a position which is grossl y rotated relative to the original. This disorder is of interest partly bec ause of its relationship to current theories of the process of object recog nition, but the range of performances typically seen, as well as its anatom ical correlates, remain obscure. We report 16 cases who produced grossly ro tated drawings of the Rey and Taylor Complex Figures. These patients were d rawn from an unselected series of 240 cases, with a wide variety of lesion types and sites. The performances of the 16 patients displayed striking sim ilarities. We describe the formal features of these drawings and plot their anatomical correlates. (C) 1998 Academic Press.
