Action Potential

A rapid rise and fall in electrical potential across a cell's membrane, enabling the transmission of signals along neurons.

Threshold Level

The minimum level of stimulus intensity required to activate a neuron or to trigger a specific physiological response.

Repolarization Phase

Phase of the action potential in which the membrane potential moves from its maximum degree of depolarization toward the value of the resting membrane potential.
