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...

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

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

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

terminals of muscle fibers have a large, saucer-like appearance. When an action potential reaches the axon terminal of a motor neuron, vesicles carrying neurotransmitters...

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

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

dynamic electrochemical phenomena called action potential and graded membrane potential. The resting membrane potential has a value of approximately -70mV or...

multiple modes of action, which makes any classification imprecise. The cardiac myocyte has two general types of action potentials: conduction system...

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...

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

occurs between the end of one action potential and the beginning of the next action potential. This increase in membrane potential is what causes the cell membrane...

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...
