Equivalent Circuits for Passive Membrane

  • Ronald J. MacGregor

Although the Nernst-Planck equations and the various constraints that might be placed upon them are interesting from the point of view of membrane physics, they become awkward and unrevealing when one is interested in signal flow over distributed neuronal structures. In such cases, equivalent electrical circuits are both convenient and revealing. However, it also is important to reconcile the circuit models with the more primitive models in order to delineate the assumptions and constraints inherent in the former. On the other hand, the circuit models themselves have a strong basis in empirical observation, and one is perfectly justified in allowing them to stand on their own merits.
