Quizplus · Accepted Answer

The two basic forms of electrical signals in the nervous system are graded potentials and action potentials. Graded potentials are small changes in electrical potential that can either depolarize (excitatory) or hyperpolarize (inhibitory) a cell. Action potentials are brief, large changes in electrical potential that allow for long-range signaling and communication between neurons.
