Membrane potential (also transmembrane potential or membrane voltage) is the difference in electric potential between the interior and the exterior of...

static membrane potential which is usually referred to as the ground value for trans-membrane voltage. The relatively static membrane potential of quiescent...

An action potential occurs when the membrane potential of a specific cell rapidly rises and falls. This depolarization then causes adjacent locations to...

They produce roughly 60–100 action potentials every minute. The action potential passes along the cell membrane causing the cell to contract, therefore...

Subthreshold membrane potential oscillations are membrane oscillations that do not directly trigger an action potential since they do not reach the necessary...

biological membrane, the reversal potential is the membrane potential at which the direction of ionic current reverses. At the reversal potential, there is...

membrane potential becomes more negative than the resting membrane potential, and this is called hyperpolarisation. To generate an action potential,...

electrophysiology, the threshold potential is the critical level to which a membrane potential must be depolarized to initiate an action potential. In neuroscience,...

Postsynaptic potentials are changes in the membrane potential of the postsynaptic terminal of a chemical synapse. Postsynaptic potentials are graded potentials, and...

bind to receptors on the postsynaptic membrane and lead to its depolarization. In the absence of an action potential, acetylcholine vesicles spontaneously...
