Which type of information can graded potentials convey to the central nervous system?

Graded potentials convey information about the strength and duration of stimuli to the central nervous system. They can vary in amplitude and are proportional to the intensity of the stimulus, allowing the nervous system to determine the intensity of sensory input. Additionally, graded potentials can summate, meaning they can combine with other signals, influencing the likelihood of generating action potentials. This modulation is crucial for sensory processing and response in the nervous system.
