Question

Quizplus · Accepted Answer

Excitatory postsynaptic potentials (EPSPs) increase the likelihood of an action potential, while inhibitory postsynaptic potentials (IPSPs) decrease the likelihood. Therefore, option C is the correct answer.

While ____ Postsynaptic Potentials Increase the Likelihood of the Postsynaptic
