The membrane potential, arising from uneven distribution of ions across cell membranes containing selectively permeable ion channels, is of fundamental importance to cell signaling. The necessity of maintaining the membrane potential may be appreciated by expressing Ohm's law as current = voltage/resistance and recognizing that no current flows when voltage = 0, i.e., transmembrane voltage gradients, created by uneven transmembrane ion concentrations, are an absolute requirement for the…

Action Potentials: Generation and Propagation
All cells maintain a voltage across their plasma membranes. Only excitable cells, however, can generate action potentials, the rapid, transient changes in membrane potential that spread along the
A classic experiment revisited: membrane permeability changes during the action potential.
This work reframed a classic experiment carried out by Hodgkin and Katz to illustrate that the membrane potential approaches the reversal potential of the ion to which it is most permeable at that instant.
A Lifetime’s Adventure in Extracellular K+ Regulation: The Scottish Connection
A lifetime spent investigating K+ buffering has seen enormous advances in glial research, from the time cells were identified as ‘presumed’glial cells or ‘silent cells’, to the present day, where glial cells are recognised as contributing to every important physiological brain function.
Membrane Potential
• Recall that the intracellular concentrations of sodium, potassium, and chloride differ from their concentrations outside the cell in the extracellular fluid. • Inside the cell, the concentration of
Disulfiram‐copper activates chloride currents and induces apoptosis with tyrosine kinase in prostate cancer cells
The mechanism that disulfiram/copper complex (DSF/Cu) treatment activates chloride channels and induces apoptosis in prostate cancer cells is elucidated.
The classics updated, or an act of electrophysiological sacrilege?
The requirement for a modern interpretation of classic electrophysiology literature is due to the manner in which electrical signals were reported, which resulted in a general breakdown in selective permeability of the membrane during the action potential and a loss of potential.

A simple, inexpensive method for teaching how membrane potentials are generated.
A simple laboratory exercise that uses an inexpensive dialysis membrane (molecular weight cutoff = 100) to illustrate the generation of membrane potentials (Vm) across plasma membranes of animal cells and uses the concept of membrane capacitance to calculate the number of ions that cross the membrane.
Xenopus laevis oocyte: using living cells to teach the theory of cell membrane potential.
A student course in membrane physiology that includes demonstration of the cell membrane potential of a living cell, the Xenopus laevis oocyte, is described, and their response to the oocyte demonstration, as evaluated by a student questionnaire, was mainly positive.

The primary role of the sodium pump as a regulator of cell volume has evolved to provide the basis for an enormous variety of physiological functions.
Origin of first cells at terrestrial, anoxic geothermal fields
This work attempted to reconstruct the “hatcheries” of the first cells by combining geochemical analysis with phylogenomic scrutiny of the inorganic ion requirements of universal components of modern cells.
Effect of nerve impulses on the membrane potential of glial cells in the central nervous system of amphibia.
In the central nervous system of the leech, which contains smooth muscle cells in its connective tissue capsule, the effect of massive neuronal activity on the resting potential of glial cells could not be studied adequately because the preparation under these conditions dislodged the electrode.
The after‐effects of impulses in the giant nerve fibres of Loligo
Reducing the concentrations of calcium and magnesium made the giant axon of Loligo spontaneously active and formed long trains of impulses in response to a single shock.

The intention is to provide students a general view of the quantitative relationship that exists between 1) transmembrane gradients for K(+ and Na(+) and 2) the relative channel-mediated permeability of the membrane to these ions.

It is suggested that Cain, through L-type Ca2+ channels and perhaps other pathways, increases KCa(i.e., I K20) and decreases voltage-dependent K+currents in this tissue and could contribute to membrane depolarization and force maintenance.
