Cell depolarization, or membrane depolarization, is a process that shifts the electrical charge distribution so that the cell is less negatively charged compared to the environment.

Get an overview of cell depolarization in our informative video lesson. Learn its properties and how it differs from repolarization, then take a quiz to review.

Learn about action potential and how to draw an action potential graph with depolarization and repolarization points. Understand what happens during depolarization.

Polarization in Neurons: At rest, a typical neuron has a resting membrane potential of approximately -70 mV. The term depolarization refers to a change in the neuronal membrane potential that makes it …
