PRCs of the neuron with different threshold dynamics. The neurons in (A) have an insensitive spike threshold to dV/dt, and in (B) have a sensitive threshold to dV/dt. For each threshold dynamic, we compute neuronal PRC at three different natural firing frequencies. The corresponding stimulation current is: Iin = 37.52, 39.31, and 40.87μ A/cm2 for βn = −5mV; Iin = 37.966, 39.70, and 41.33μ A/cm2 for βn = −7mV; Iin = 38.74, 40.28, and 41.94μ A/cm2 for βn = −9mV; Iin = 41.17, 41.81, and 42.87μ A/cm2 for βn = −11mV; Iin = 42.63, 43.20, and 44.25μ A/cm2 for βn = −13mV; Iin = 45.478, 45.688, and 46.5μ A/cm2 for βn = −15mV. All PRCs are computed in the case of no noise, i.e., σ = 0μ A/cm2.
