                       Study of the Frontal Speech Area with

                      TransCranial Magnetic Stimulation (TMS)

                    Department of Neurology, Univ. of Minnesota

                         and MINCEP, Minneapolis, MN 55455

                                 research done by

                Alvaro Pascual-Leone, Anil Dhuna and John R. Gates


       TransCranial magnetic stimulation   (TMS)  at  8  to  25  Hertz  was

       performed on 4 subjects over the frontal area.


       Over each side stimulation was performed  with  the  11  CM diameter

       coil held flat  on  the scalp and the outer edge consecutively  held

       over the 16  positions  of a 4 X 4 grid with 1.5 CM distance between

       grid points.  The anterior-inferior corner of the grid was electrode

       position F7.


       All subjects were  being  evaluated   for   surgical   treatment  of

       medically intractable epilepsy.     Intracarotid     amytal     test

       demonstrated left hemisphere speed dominance in all.


       TMS induced speech  arrest  in all patients when applied to a SINGLE

       GRID POSITION over the LEFT HEMISPHERE.


       In all subjects, this position WAS  DIFFERENT  and anterior to those

       that induced laryngeal or contralateral face and hand movements.


       This study demonstrates that TMS is capable of IDENTIFYING a frontal

       area different from the motor cortex, which when stimulated  INDUCES

       SPEECH ARREST.
