Question

Quizplus · Accepted Answer

Graded potentials are local changes in membrane potential that occur in varying degrees of magnitude. They are not action potentials and can be both depolarizations and hyperpolarizations. The magnitude of the graded potential changes with the strength of the stimulus, and they may or may not lead to the generation of an action potential.
