depolarizations
Membrane potential reversals
Depolarizations are instances of reducing or reversing polarity—the state of having opposite extremes.
In politics and culture, depolarization means moving away from sharply divided camps toward more moderate or unified positions.
In physiology, depolarization is the electrical change in a nerve or muscle cell that triggers activity: The depolarizations of cardiac cells create the heartbeat.
The plural typically appears in technical contexts describing multiple such events.
