Power-Law Dynamics of Membrane Conductances Increase Spiking Diversity in a Hodgkin-Huxley Model
Fig 2
The effect of power-law behaving Hodgkin-Huxley gating variables on the shape and properties of the action potential.
(A) Action potential shapes generated with the minimum input current as a function of the order of the fractional derivative (η) for the respective gate. (B) The action potential current threshold as a function of input current and η. (C) Phase plot of the action potentials generated at minimum input current as function of η. The red squares indicate the crossing of threshold detection (dv/dt > 20 mV/ms). (D) The voltage threshold calculated from the phase plots in C.
