  • Neural engineering

Background:

  • Accurate modeling of nerve cell activation is crucial for understanding neural interfaces.
  • Existing complex neuron models present computational challenges for simulating myelinated fibers.

Purpose of the Study:

  • To adapt a simple spiking cell model for extracellular current activation.
  • To provide a simplified simulation approach for myelinated nerve cells at the electrode-tissue interface.

Main Methods:

  • Modification of a standard simple spiking cell model.
  • Implementation of extracellular current as a stimulus.
  • Substitution of complex neuron models with the modified simple model at activation sites.

Main Results:
