Nano-scale solution of the Poisson-Nernst-Planck (PNP) equations in a fraction of two neighboring cells reveals the magnitude of intercellular electrochemical waves

Largest deviations from rest in the extracellular potential and ion concentrations outside of the Na+ channel clusters in simulations with different widths of the extracellular space between the cells, Le, and different sizes of the Na+ channel clusters.
The full lines show the solution outside of the Na+ channel cluster of the pre-junctional cell, which has open Na+ channels. The dotted lines show the solution on the other side of the extracellular space, outside of the post-junctional cell, which has closed Na+ channels.
