What is the all-or-none law for nerve cells?

Posted December 6, 2023


Answer

The all-or-none law for nerve cells states that the strength with which nerve cells respond to a stimulus remains the same regardless of the strength of the stimulus causing them to fire. The strength of the stimulus only needs to be above a certain threshold to trigger a reaction. It does not influence the strength of the reaction.
