Membrane potential - the difference in electrical charge between the inside and outside of a neuron (or other cell).
The membrane potential is the result of the diffusive transport of ions through a membrane under constant temperature and pressure and without electrical current and the Donnan potentials. From: Membrane Science and Technology, 2004 About this pageSet alert ...

The article quantifies these principles using a range of simple equations such as Ohm’s Law, the Nernst equation, and the Goldman–Hodgkin–Katz (GHK) equation, and illustrates how to calculate the number of ions flowing in or out of a cell during typical membrane potential changes. The...

A convenient framework for understanding permeation has been provided by the inhomo- geneous solubility-diffusion model6, which relates the resistance to permeation in the direction, z, normal to the membrane to the position-dependent diffusivity of the substrate, D(z), and the potential of mean...
Although the present study did not assess the reversibility of AnkG palmitoylation, regardless of any potential reversible nature, AnkG may be primed to accept the Cys modification in the juxtamembrane region; once that happens, AnkG becomes a rigid structural base for a membrane-excitation ...
