Graded Potentials ACTUAL Exam Questions and CORRECT Answers Graded potentials are - CORRECT ANSWER - Brief Short distance signals within a neuron. Short-lived, localized changes in membrane potential, usually in dendrites or the cell body. They can be either depolarizations or hyperpolarizations. These changes cause current flows that decrease in magnitude with distance. Action Potentials are - CORRECT ANSWER - Brief Long distance signals within a neuro
