Mirror phenomena in language and nonverbal activities--a case report.

A case is described of a 38-year-old, left-handed female who demonstrated mirror phenomena for both language and non-motor, nonverbal material. She mirror-wrote with her left hand with normal right-hand writing. Mirror-reading as well as object and spatial reversals were revealed. These data are consistent with bilateral representation of visual engrams, with one hemisphere containing a mirror-reversed representation of the other.
