Most texts on neurons give the value of the membrane potential and do not state the absolute values of the intracellular and extracellular potentials in a neuron. I understand that this is because the membrane potential is all that is needed to understand propagation of impulses along a neuron. However, I am curious about the absolute intracellular and extracellular potentials in a resting neuron. Have they been determined? If yes, what are their values if we take our reference of zero potential as a point infinitely far away from the neuron?
