Figure 2. Summary of the two-domain electrodiffusive formalism.

Figure 2

The set of equations summarizes the electrodiffusive formalism. In equations containing the symbol “±”,“+” should be used for intracellular domain (Inline graphic) and “−” should be used for the extracellular domain (Inline graphic). The formalism is general to the choice of membrane mechanisms. Inline graphic, representing system specific membrane mechanisms (ion pumps, ion channels, cotransporters ect.), must to be specified by the user. External input to the system must also be specified. The input must be locally electroneutral, i.e., must fulfill Inline graphic.
