The threshold value is the level of depolarization required to trigger an action potential; stimuli below this threshold do not generate an action potential, and the size of a stimulus above the threshold does not affect the action potential itself.
- level of depolarisation at which action potential is generated - below this, action potential is not generated (size of stimulus above threshold does not affect action potential)
