Graded potentials are changes in the membrane potential of a neuron or other excitable cell that vary in size (or "grade") and occur in response to stimuli. These changes are typically localized and can either be depolarizing or hyperpolarizing. ### Key Features of Graded Potentials: 1. **Magnitude**: The amplitude of a graded potential can vary depending on the strength of the stimulus. A stronger stimulus produces a larger potential change.
