Variation in frequency as a function of length for different diffusivities in the advection-diffusion model. Other parameters are the same as in Fig. 5. (a) Plot showing that the frequency is insensitive to D except at small axonal lengths. (b) Plot showing that the main effect of diffusivity is to modify the critical length at which a Hopf bifurcation occurs. (A zero frequency indicates that the system is operating below the Hopf bifurcation point, so there are no oscillations.)
