Ai: The oscillators with voltage trajectories
and
and phase difference
determine the membrane potential at the ends of a cable with electrotonic length
. Aii: The interaction function
gives the phase shift of oscillator A as a function of
. This interaction function is shifted along the
-axis by the parameters
and
, which capture the oscillator and cable properties, respectively. Aiii: The stable phase-locked solution is determined by

and is either at

(e.g. for the dash-dotted curve). Aiv: The stable phase-locked solution as a function of
. The value of
uniquely determines where the in-phase (black solid line) or the anti-phase solution (red dotted line) is stable, given a fixed value of
. B:
as a function of the electrotonic distance
between the oscillators,
ms and
ms (dotted line in panel D). For illustrative purposes we chose
so that the stable in-phase and anti-phase solutions are given by the white and gray areas, respectively. C:
