POINT!
| When the negative resting intracellular potential is smaller (larger), less (more) stimulation is needed for action potential generation, making the cell less (more) stable. |
narrated animation
When the resting membrane potential is increased, more stimulus is needed to reach the firing level. This means that the stability is increased.
When the resting membrane potential is decreased, less stimulus is needed to reach the firing level. This means that the stability is decreased.
