Chapter 3 The triple stimulation technique to study corticospinal conduction

Abstract

Publisher Summary This chapter describes the triple stimulation technique (TST) and discusses its yield and limitations in the study of corticospinal conduction. The TST improved the understanding of corticospinal conduction. It explained the small size and variable configuration of the conventional motor evoked potentials (MEPs) and demonstrated that transcranial stimuli were able to depolarize virtually all motor units of the target muscle. The TST markedly improves the study of corticospinal conduction. It allows better detection and quantification of corticospinal conduction deficits. It offers interesting perspectives for studies that conventional MEPs do not allow. In particular, it may be used as an objective method of assessment of the effects of treatments. Eventually, it will play a role in the further understanding of the physiology of the corticospinal conduction.
