Ion Channel Density Regulates Switches between Regular and Fast Spiking in Soma but Not in Axons

Figure 12

Bifurcation curves and the three-root solution space for the myelinated axon model.

I_stim− diagrams at = 1200 S/m². The thick continuous line defines the region associated with three-root solutions of Equation 14. The thin continuous line is the Andronov-Hopf bifurcation curve and the hatched line is the double limit cycle bifurcation curve. (A) An overall perspective. (B) A detailed view of the cusp of the three-root solution space to describe the three subregions. The Bogdanov-Takens bifurcation point is marked.
