Abstract

“Mirror-writing” is the simultaneous process of reversing individual letters and composing word strings in reverse direction. It is reported that the lesions which cause “mirror-writing” are left parietal lobe, left basal ganglia, right supplementary motor area, left supplementary motor area, left cingulate gyrus, and left angular gyrus. To explain this phenomenon, several theories have been proposed such as the motor, the visual dominance, the supplementary motor area, the visio-spatial, the visual word- form, the hemisaptial factor or directional and the reflected graphemic representation hypotheses. With reviewing some of literatures, we present a case of “mirror- writing” of posterior corpus callosum lesion which is not included in the aforementioned those.
