English
A number of ionotropic receptors have been identified to contribute to anoxic depolarization of nerve cell membrane.

Physiologically, the normal electrical depolarization wave is delayed at the atrioventricular node to allow the atria to contract before the ventricles.
en.wikipedia.org
Spectra acquired with the analyzer set at both perpendicular and parallel to the excitation plane can be used to calculate the depolarization ratio.
en.wikipedia.org
They have a crucial role in excitable neuronal and muscle tissues, allowing a rapid and co-ordinated depolarization in response to triggering voltage change.
en.wikipedia.org
These channels require a strong depolarization in order to be activated.
en.wikipedia.org
When chloride enters the nerve cell, the cell membrane potential hyperpolarizes thereby inhibiting depolarization, or reduction in the firing rate of the post-synaptic nerve cell.
en.wikipedia.org
The entry of potassium causes a local depolarization that propagates electrotonically through the glial cell network which causes net driving force of potassium out of the glial clls.
en.wikipedia.org
It is unique because it is open at rest and even more likely to be open during depolarization.
en.wikipedia.org
Possible explanations include shortening of ventricular refractoriness (i.e. delayed reactivation of sodium channels) and altered sequence of depolarization and hence inhomogeneity of ventricular repolarization.
en.wikipedia.org
That influence will be electrotonic; depolarization of the surrounding field will induce a partial depolarization of the pacemaker cells.
