Question

Quizplus · Accepted Answer

Graded potentials can do all of the listed actions. They can initiate an action potential by depolarizing the membrane to the threshold voltage. They can also hyperpolarize the membrane, which inhibits the firing of an action potential. Graded potentials can be excitatory and are called EPSPs, or inhibitory and are called IPSPs. Therefore, all the statements are true.
