Equations for the membrane potential

Biophysics, 2009
The problem of an electric signal propagating over a thin layer modeling the cell membrane is considered in the electrostatic approximation. At both sides of the membrane there are bulk conductors with different properties. Various types of boundary conditions are examined.

Membrane Potential Imaging

1991
There are two populations of scientists who have, respectively, employed two different classes of voltage-sensitive dyes. The larger group, of cell biologists, has primarily used slow (response time > s) redistribution dyes for measurements of membrane potential changes in suspensions of cells or energytransducing organelles (Freedman and Laris, 1981 ...

Membrane potentials inStentor coeruleus

Protoplasma, 1971
The membrane potential ofStentor coeruleus was measured by means of glass microelectrodes. The tips of the electrodes had a diameter of 2 μ, and were filled with 0.1 M KCl. The maximum value of the potential is −30.8±8.6 mV and is reached within 600–800 msec after electrode insertion; the potential then decreases to a negative value of a few mV within ...

Generation of the Membrane Potential

2003
Knowledge of the existence of bioelectric potentials must certainly go back to the first unfortunate encounters that people had with electric fish, but an understanding of the origin of these potentials awaited the advances in physical chemistry that occurred near the end of the 19th century.

On Membrane Potentials and Their Measurements

1979
More than a century ago, the major importance of electrical properties of biological membranes was recognized and many evidences were experimentally pointed out.
