Abstract

Objective: The relationship between the accessory nerve excitation site and the magnetic field direction was investigated to prove whether the cranial nerve excitation site to the transcranial magnetic stimulation is constant or not. Methods: Compound muscle action potentials (CMAPs) elicited by the transcranial magnetic stimulation were recorded from the trapezius muscles of 7 adult cats. The waveforms of CMAPs were detected before craniectomy, after craniectomy, and after cutting the accessory nerve at the C1, at the jugular tubercle, and at the jugular foramen. The optimal orientation was determined by rotating the coil clockwise in increments of 22.5 degrees from the rostral direction. Results: The accessory nerve was stimulated by the magnetic stimulation atthe C1, at the jugular tubercle or at the jubular foramen, and these excitation sites varied with coil orientation. The average angles of the optimalorientation of the magnetic coil were 77.1 degrees for C1, 122.1-263.6 degrees for the jugular tubercle, and 308.6-32.1 degrees for the jugular foramen. Conclusions: The accessory nerve excitation site varied with the orientation of the magnetic coil. This study suggested the possibility of a variety of the cranial nerve excitation sites to the transcranial magnetic stimulation. (C) 1999 Elsevier Science Ireland Ltd. All rights reserved.
