Definitions:

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.

Threshold

The minimum level of stimulation required to trigger a neural impulse or a response in other signal-transmitting systems.

Voltage-Gated Channel

A type of ion channel that opens or closes in response to changes in membrane potential, critical for nerve impulse transmission.
