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

The maximum of the absolute value of the derivative of the potential and the concentrations with respect to time and with respect to x in the PNP simulation reported in Fig 8.
In this simulation, the K+ channels are open for both cells, and a Na+ channel cluster consisting of 196 channels are opened for the pre-junctional cell. The extracellular space width is Le = 10 nm. As a comparison, the transmembrane electric field is in the range of 15 mV/nm for a membrane potential of −90 mV.
