Interneurons typically respond to chemical (neurotransmitter) stimulation with a change in membrane potential that is graded with the stimulus intensity. This means that the change in membrane potential can vary in size depending on the strength of the stimulus; stronger stimuli will produce larger changes in membrane potential. This graded potential can be subthreshold, meaning it may not always reach the threshold needed for firing an action potential, which is an all-or-nothing response. Therefore, the correct answer is:
- graded with the stimulus intensity.
