Nerve conduction velocity selective recording using a multi-contact cuff electrode - A case study of in-vitro vagus nerve preparation

Abstract

In this study, a method for nerve conduction velocity selective recording using a multi-contact cuff electrode is evaluate using an in-vitro vagus nerve preparation. A delay adder only and a delay adder followed by a matched filter tuned to the different components of the elicited compound action potentials (CAP) were applied to extract the nerve conduction velocity (CV). Both filters were able to single out the conduction velocity of the fastest component of the elicited CAP. Selective tuning to the CV of the other components was only possible when considering corresponding sub-regions of interest for each particular component of the CAP. © 2011 Springer-Verlag.
