Fix the electric field amplitude (frequency), the average firing rate versus the frequency (amplitude) in different extracellular resistance. a The fixed amplitude A = 300 mV, b the fixed frequency f = 1 Hz. As the legend shows, the three colors denote different extracellular resistance values. (Color figure online)
