Bu çalışmada bimastoidal beyin sapı stimulasyonu için yüksek akımlı ve
kısa süreli akım veren bir stimulator kullanıldı. Stimulasyon için anod sağ
tarafta olmak üzere yüzeyel halka elektrodlar her iki mastoid proçesin
posterior köşesine yerleştirildi. Kayıtlama için yüzeyel halka elektrodlar
soleus ve tibialis anterior kaslarına yerleştirildi. Beyin sapının elektriksel
uyarımı ile piramidal yolun direkt olarak serviko-meduller bileşke düzeyinden
uyartıldığı düşünülmektedir.

Brainstem Motor Evoked Potential

Öz

In this study we used an electrical stimulator which gives high
voltage, short time duration for bimastoidal brainstem stimulation. Each of the
surface electrod pairs was placed at the posterior edge of each mastoid
process. The anodal electrod was right side. Surface EMG electrod pairs were
placed over the long axis of anterior tibial muscle and belly of the soleus
muscle for recording. The electical brainstem stimulation is considered to
activate the corticospinal tract directly near the cervico-medullary junction.
