Graded Potentials, Action Potentials&SynapseGraded Potentials - correct answer A small deviation from the RMP that makes the membrane either more polarized (more negative inside=hyperpolarizing) or less polarized (less negative inside=depolarizing). Hyperpolarizing Graded Potentials - correct answer When the response makes the membrane more polarized (more negative inside). Occurs in soma and dendrites of a neuron. Depolarizing Graded Potentials - correct answer When the response makes the...
