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

Unlike the action potential in skeletal muscle cells, the cardiac action potential is not initiated by nervous activity. Instead, it arises from a group...

potential is about −90 mV at rest, which is close to the potassium reversal potential. When an action potential is generated, the membrane potential rises...

electrocardiography, the atrial action potential are action potentials that occur in the heart atrium. They are similar to ventricular action potential with the exception...

postsynaptic potential (IPSP) is a kind of synaptic potential that makes a postsynaptic neuron less likely to generate an action potential. The opposite...

The compound muscle action potential (CMAP) or compound motor action potential is an electrodiagnostic medicine investigation (electrical study of muscle...

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

A pacemaker action potential is the kind of action potential that provides a reference rhythm for the network. The pacemaker potential is the slow depolarization...

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

which is potential can theoretically be made actual by taking the right action; for example, a boulder on the edge of a cliff has potential to fall that...

excitatory postsynaptic potential (EPSP) is a postsynaptic potential that makes the postsynaptic neuron more likely to fire an action potential. This temporary...

An action potential pulse is a mathematically and experimentally correct Synchronized Oscillating Lipid Pulse coupled with an Action Potential. This is...

postsynaptic potentials (EPSPs). Depolarizing local potentials sum together, and if the voltage reaches the threshold potential, an action potential occurs...

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 stimulus...

by action potentials. However, all action potentials are begun by electrotonic potentials depolarizing the membrane above the threshold potential which...

and should not be confused with action potentials although their function is to initiate or inhibit action potentials. They are caused by the presynaptic...

Neural backpropagation is the phenomenon in which, after the action potential of a neuron creates a voltage spike down the axon (normal propagation), another...

membrane potential (or resting voltage), as opposed to the specific dynamic electrochemical phenomena called action potential and graded membrane potential. Apart...
