  • Title: The excitation functional for magnetic stimulation of fibers.
    Author: Suárez-Bagnasco D, Armentano-Feijoo R, Surez-Antola R.
    Journal: Annu Int Conf IEEE Eng Med Biol Soc; 2010; 2010():4829-33. PubMed ID: 21097300.
    Abstract:
    Threshold problems in electric stimulation of nerve and muscle fibers have been studied from a theoretical standpoint using the excitation functional. Here the excitation functional is extended to magnetic stimulation of excitable nerve and muscle fibers. A unified derivation of the functional is done, for (non myelinated) nerve and muscle fibers, by means of the nonlinear cable equation with a Fitzhugh-Nagumo membrane model and a generalized Rattay's activating function. The identification problem of the excitation functional for magnetic stimulation, from strength-duration experimental data, is briefly considered.
