  • Model of Impedance Changes in Unmyelinated Nerve Fibres

    Electrical impedance tomography produces cross-sectional images of the compound action potential in peripheral nerve; it has potential to provide images of active fascicles in autonomic nerves. It could be used in electroceuticals for selective stimulation of nerve fascicles and so avoid off-target effects.
    For this, the EIT parameters must be optimised. This has been aided by development of accurate FEM models of unmyelinated nerve fibres bi-directionally coupled with the external space. The models agreed with experiments and could serve as a basis for optimising EIT imaging and consequent selective stimulation.
