  2. Activating Function: Contact Distance (mV/cm2) • Maps the change in potential on the nerve. • A function of position relative to electrode. • Shows the level depolarization and hyperpolarization. • Any depolarization above threshold causes neurons to fire. Modeling: E. Ranu. Modeling based on: Rattay, F, “Analysis of models for extracellular fiber stimulation,” IEEE Trans Biomed Eng., Jul;36(7):676-82, 1989.
