Effect of high-frequency stimulation on nerve pulse propagation in the FitzHugh–Nagumo model

Abstract: We consider the FitzHugh-Nagumo model axon under action of a homogeneous high-frequency stimulation (HFS) current. Using a multiple scale method and a geometrical singular perturbation theory, we derive analytically the main characteristics of the traveling pulse. We show that the effect of HFS on the axon is determined by a parameter proportional to the ratio of the amplitude to the frequency of the stimulation current. When this parameter is increased, the pulse slows down and shrinks. At some threshold valu… Show more

“…In this case, the high-frequency term in Eq. (1a) can be eliminated via a two-scale expansion method [29] in a way similar to what has been done in our recent paper [10] for the continuous version of FHN equations. In the Appendix, however, we present an alternative approach based on the method of averaging [28].…”

“…In the recent papers [14,15] detailed investigations, both analytical and numerical, have been carried out towards understanding of the mechanism of the existing DBS therapy technique. We hope that search for alternative methods, in particular using experimental approach, can contribute to the problem of the treatment of the Parkinson disease.…”
