Definitions:

Local Potential

Small changes in membrane potential that are crucial in the propagation of nerve impulses and can lead to an action potential if they reach a certain threshold.

Depolarization Event

A temporary change in a cell's membrane potential, making it more positive, typically associated with the initiation of nerve impulses or muscle contractions.

Stimulus Strength

The intensity of a stimulus, which can influence the magnitude of response in sensory and other physiological systems.

Resting Membrane Potential

The electrical potential difference across the plasma membrane when a cell is in an unstimulated condition.
