What type of electric potential increases the likelihood that the postsynaptic neuron will fire?

Question

Quizplus · Accepted Answer

An excitatory postsynaptic potential (EPSP) is a type of electric potential that increases the likelihood that the postsynaptic neuron will fire. This occurs when positively charged ions enter the postsynaptic neuron, reducing the membrane potential and making it more likely to reach the threshold for an action potential. All-or-none potentials refer to the nature of action potentials themselves and not the postsynaptic potential. Inhibitory postsynaptic potentials (IPSPs) decrease the likelihood of the postsynaptic neuron firing, while excitatory presynaptic potentials are not a type of electric potential associated with the postsynaptic neuron firing.
