Abstract

Mirror writing is script that runs in the direction opposite to normal, with individual letters also reversed. A Right handed woman suddenly developed mirror-writing. After traumatic brain injury without definitive lesions on MRI, she could not discriminate between right and left by herself. Several theories, including motor, visual dominance, spatial disorientation and supplementary motor hypotheses, have been proposed to explain such. We believe that availability of mirror engrams induce reversal of normal left-to-right writing pattern including mirror-writings.
