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,...

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...

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

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...

to a more positive membrane potential occurs during several processes, including an action potential. During an action potential, the depolarization...

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...

changes in membrane conductance do not contribute. Neurons and other excitable cells produce two types of electrical potential: Electrotonic potential (or graded...

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...

basic voltage clamp will iteratively measure the membrane potential, and then change the membrane potential (voltage) to a desired value by adding the necessary...

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...

pacemaker potential (also called the pacemaker current) is the slow, positive increase in voltage across the cell's membrane (the membrane potential) that...

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...

often bring the membrane potential of the sensory receptor towards the threshold for triggering an action potential. Receptor potential can work to trigger...

in membrane potential that returns it to a negative value just after the depolarization phase of an action potential which has changed the membrane potential...

A membrane transport protein (or simply transporter) is a membrane protein involved in the movement of ions, small molecules, and macromolecules, such...

needed] Many cells have resting membrane potentials that are unstable. It is usually due to ion channels in the cell membrane that spontaneously open and...

constant membrane potential; this is known as a resting potential. This resting phase (see cardiac action potential, phase 4) ends when an action potential reaches...

cell's membrane potential back to its resting membrane potential. When the cell's membrane voltage overshoots its resting membrane potential (near -60...

Synaptic potential refers to the potential difference across the postsynaptic membrane that results from the action of neurotransmitters at a neuronal...

cell membrane (also known as the plasma membrane or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that...
