Integrative action of axonal membrane explored by trains of subthreshold stimuli applied to the peripheral nerve

Highlights • Our results revealed an under-recognized phenomenon of the excitability changes in the peripheral nerve caused by a train of subthreshold stimuli. • The summation effect of the subthreshold train of stimuli could increase the resting membrane potential to the firing level. • This phenom...

Beschreibung
Zusammenfassung:	Highlights • Our results revealed an under-recognized phenomenon of the excitability changes in the peripheral nerve caused by a train of subthreshold stimuli. • The summation effect of the subthreshold train of stimuli could increase the resting membrane potential to the firing level. • This phenomenon can explain some neurophysiologic phenomena during intraoperative monitoring.
