Definitions:

Depolarization

A decrease in the difference in electrical charge across a cell's plasma membrane, making the inside of the cell less negative compared to the outside.

Hyperpolarization

Hyperpolarization is an increase in a cell's membrane potential, making it more negative and less likely to fire an action potential.

Repolarization

The process of restoring the negative charge inside a neuron or muscle cell after depolarization, preparing it for another action potential.

Electric Signals

are impulses of charged particles, such as ions, used by neurons and other cells to communicate and perform physiological functions.
