Outline of Final Research Achievements

The present study was designed to clarify peak latency, source current orientation and hemispheric laterality of the initial cortical response of SEFs for the stimulation tongue and flap tongue. In 8 healthy subjects, initial cortical response of tongue SEFs was clearly measured in 6 out of 8 hemispheres contralateral to the stimulated side. Latency of the response was 15.8 +/- 0.9 ms (mean +/- standard error) and source current orientation was anterior. In 15 patient subjects, initial cortical response of healthy tongue SEFs was clearly measured in 12 out of 15 hemispheres contralateral to the stimulated side. Latency of the response was 16.4 +/- 0.9 ms (mean +/- S.E.) and source current orientation was anterior. ECDs are localized on the central sulcus. In 12 of 15 patients we recorded SEF in SI or SII for flap tongue electrical stimulation.
