title: Heterotopic striated muscle on the surface of the brain.
abstract: Heterotopic tissue, identified by both light and electron microscopy as cardiac muscle, was detected at autopsy on the surface of the right superior temporal gyrus of a 73-year old female patient. The cells of the heterotopic tissue were interconnected by intercalated discs and the fibres contained regularly cross-striated, contracted, or relaxed myofibrils indicating a continuing contractile activity until the time of death.
