Definitions:

Membrane Potential

The electrical potential difference across a cell's plasma membrane, critical for the conduction of impulses in neurons and muscle cells.

Depolarization

The process in which the electrical charge of a cell membrane becomes less negative, often leading to the initiation of an action potential.

Repolarization

The process of restoring the negative charge inside the membrane of a neuron or muscle cell after depolarization.

Afterpotential

Afterpotential refers to the changes in membrane potential that follow an action potential in a neuron, often leading to either hyperpolarization or depolarization.
