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...
Subthreshold membrane potential oscillations are membrane oscillations that do not directly trigger an action potential since they do not reach the necessary...
electrophysiology, the threshold potential is the critical level to which a membrane potential must be depolarized to initiate an action potential. In neuroscience,...- 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,...
They produce roughly 60–100 action potentials every minute. The action potential passes along the cell membrane causing the cell to contract, therefore...

This temporary depolarization of postsynaptic membrane potential, caused by the flow of positively charged ions into the postsynaptic...- 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...
Depolarization (redirect from Membrane depolarization)to a more positive membrane potential occurs during several processes, including an action potential. During an action potential, the depolarization...
Mitochondrion (redirect from Mitochondrial membrane)there is a membrane potential across the inner membrane, formed by the action of the enzymes of the electron transport chain. Inner membrane fusion is...- membrane potential is about −90 mV at rest, which is close to the potassium reversal potential. When an action potential is generated, the membrane potential...
- changes in membrane conductance do not contribute. Neurons and other excitable cells produce two types of electrical potential: Electrotonic potential (or graded...
- Hyperpolarization (biology) (category Membrane biology)change in a cell's membrane potential that makes it more negative. It is the opposite of a depolarization. It inhibits action potentials by increasing the...
basic voltage clamp will iteratively measure the membrane potential, and then change the membrane potential (voltage) to a desired value by adding the necessary...- A membrane transport protein (or simply transporter) is a membrane protein involved in the movement of ions, small molecules, and macromolecules, such...
membrane potential can be measured. Typically, the resting membrane potential of a healthy cell will be -60 to -80 mV, and during an action potential...
