    • Of course, this is also an approximation. In future work we will replace the discrete cable theory with the modified cable theory 6, which incorporates both the discretizing nature of the gap junctions as well as the continuous propagation within a cell

    • by adding a random potential force term to the Langevin equations (10) and (15). For variances of the random potential smaller than the energy fluctuations (Formula presented), as in the present investigation, the overall picture of kink dynamics does not change (the diffusion parameters, though, must be rescaled to account for spatial disorder). In the opposite limit and for (Formula presented), disorder may provide more efficient a kink pinning mechanism than discreteness
    • Diffusion of kinks in a random landscape (like the quenched noise due to resonator array dishomogeneities) has been studied, e.g., by F. Marchesoni, Europhys. Lett. 8, 83 (1989), by adding a random potential force term to the Langevin equations (10) and (15). For variances of the random potential smaller than the energy fluctuations (Formula presented), as in the present investigation, the overall picture of kink dynamics does not change (the diffusion parameters, though, must be rescaled to account for spatial disorder). In the opposite limit and for (Formula presented), disorder may provide more efficient a kink pinning mechanism than discreteness.
