<rdf:value>
In their 1952 masterpiece, Hodgkin & Huxley specified the experimentally observed range for each of the ionic current reversal potentials. Given the Nernst equation, the observed variation is most likely due to changing intra- or extracellular ion concentrations. Thus we examine the effect of ion concentration by altering the reversal potential of each current.
