Reversal potential — This article is about the biological application of the Nernst equation. For the general equation, see Nernst equation. In a biological membrane, the reversal potential (also known as the Nernst potential) of an ion is the membrane potential at… … Wikipedia
Reversal — A change in the direction of a price trend. On a price chart, reversals undergo a recognizable change in the price structure. An uptrend, which is a series of higher highs and higher lows, reverses into a downtrend by changing to a series of… … Investment dictionary
Membrane potential — Differences in concentration of ions on opposite sides of a cellular membrane lead to a voltage called the membrane potential. Many ions have a concentration gradient across the membrane, including potassium (K+), which is at a high inside and a… … Wikipedia
Resting potential — The relatively static membrane potential of quiescent cells is called the resting membrane potential (or resting voltage), as opposed to the specific dynamic electrochemical phenomena called action potential and graded membrane potential. Apart… … Wikipedia
Ventricular action potential — At rest, the ventricular myocyte membrane potential is about 90 mV, which is close to the potassium reversal potential. When an action potential is generated, the membrane potential rises above this level in four distinct phases.The beginning of… … Wikipedia

action potential — Physiol. the change in electrical potential that occurs between the inside and outside of a nerve or muscle fiber when it is stimulated, serving to transmit nerve signals. Cf. nerve impulse. [1925 30] * * * Brief (about one thousandth of a… … Universalium
Magnetization reversal by circularly polarized light — Discovered only recently (2006) by C.D. Stanciu and F. Hansteen and published in Physical Review Letters[1][2] this effect is generally called all optical magnetization reversal. This magnetization reversal technique refers to a method of… … Wikipedia
action potential — n a momentary reversal in the potential difference across a plasma membrane (as of a nerve cell or muscle fiber) that occurs when a cell has been activated by a stimulus called also spike potential compare RESTING POTENTIAL see afterpotential … Medical dictionary
Periodic current reversal — (PCR) is a current modulation technique that can be used in various electrochemical processes.In the most basic sense PCR simply means that the electrical current applied to the cell is reversed periodically but unlike pure AC the average (nett)… … Wikipedia
