What is "in a graded potential?

In a graded potential, the strength of the electrical signal varies depending on the magnitude of the stimulus. This is in contrast to an action potential, where the signal is either at maximum strength or not present at all. Graded potentials can be depolarizing or hyperpolarizing, meaning they can either bring the cell closer to or further from the threshold for generating an action potential. Graded potentials occur in various types of cells, including neurons and muscle cells, and are important for processes such as sensory perception and synaptic transmission. They are typically shorter-lived and smaller in amplitude than action potentials.
