any kind of anion. The opposite of a depolarization is called a hyperpolarization. Usage of the term "depolarization" in biology differs from its use in...

an ECG: The P wave, which represents depolarization of the atria. The QRS complex, which represents depolarization of the ventricles. The T wave, which...

A depolarizer or depolariser, in electrochemistry, according to an IUPAC definition, is a synonym of electroactive substance, i.e., a substance which...

or spreading depolarization (SD) is a wave of electrophysiological hyperactivity followed by a wave of inhibition. Spreading depolarization describes a...

Look up depolarization in Wiktionary, the free dictionary. Depolarization or depolarizer may refer to: Depolarization, a decrease in the absolute value...

liquid crystals. It is also possible to depolarize light using fiber optics. Relatively high degree of depolarization is also achieved by light passing through...

stimulus, there is an efflux of Chloride from the cell, resulting in depolarization of the cell. This causes the GDPs. Once the KCC2 expression is relatively...

currents could be invoked simply by depolarization of the target cell, this phenomenon was termed depolarization-induced suppression of inhibition. While...

perpendicular, would have a depolarization ratio of 1/10 = 0.1, which corresponds to a highly polarized band. The value of the depolarization ratio of a Raman band...

receptor to open the channel and cause depolarization of the end plate, which later spread to and result in depolarization of adjacent membranes. As a result...

will be decreased as opposed to increased. Possibly resulting from the depolarization of the S4 segments and the little time given for inactivation. For long...

A quantum depolarizing channel is a model for quantum noise in quantum systems. The d {\displaystyle d} -dimensional depolarizing channel can be viewed...

atrial depolarization, which results in atrial contraction, or atrial systole. The P wave is a summation wave generated by the depolarization front as...

a Ca2+ mediated depolarization, which causes voltage gated Na+ channels to open, resulting in action potentials. This depolarization is followed by a...

wave (the onset of atrial depolarization) until the beginning of the QRS complex (the onset of ventricular depolarization); it is normally between 120...

larger the stimulus, the greater the depolarization, or attempt to reach threshold. The task of depolarization requires several key steps that rely on...

pacemaker phase, or slow diastolic depolarization or phase 4. The duration of this slow diastolic depolarization (pacemaker phase) thus governs the cardiac...

action potential consists of three phases. Phase one is depolarization. During depolarization, voltage-gated sodium ion channels open, increasing the...

enable them to locally depolarize adjacent cells. Gap junctions allow the passage of positive cations from the depolarization of the pacemaker cell to...

Anoxic depolarization is a progressive and uncontrollable depolarization of neurons during stroke or brain ischemia in which there is an inadequate supply...

whereby losing their net alignment and thus the material become depolarized. This depolarization can be measured if the material is sandwiched between two ohmic...

End plate potentials (EPPs) are the voltages which cause depolarization of skeletal muscle fibers caused by neurotransmitters binding to the postsynaptic...

complex, and the sinus rhythm therefore gives rise to the whole heart's depolarization. Exceptions to this include complete heart block and certain ventricular...

of sodium leads to a short term depolarization of the postsynaptic neuron and an EPSP. While a single depolarization of this kind may not have much of...

specific cell rapidly rises and falls. This depolarization then causes adjacent locations to similarly depolarize. Action potentials occur in several types...

initial membrane depolarization leads to uncontrolled deflection of the membrane potential to near VNa. The initial depolarization must reach or surpass...

ions entering the cell cause the depolarization characteristic of an action potential. Like skeletal muscle, depolarization causes the opening of voltage-gated...

retrograde flow to the atria causing depolarization prior to the ventricular contraction. Since the depolarization is occurring in the opposite direction...

efflux of Na+ through the connexon at peak depolarization causes the conduction of cell to cell depolarization, not potassium.) These connections allow...

myocytes, allowing for rapid, coordinated, and synchronous physiologic depolarization of the ventricles.[citation needed] When a bundle branch or fascicle...
