What is a change in the postsynaptic potential that brings membrane potential closer to threshold called?
A) hyperpolarizing postsynaptic potential
B) excitatory postsynaptic potential
C) suprathreshold postsynaptic potential
D) inhibitory postsynaptic potential
E) inhibitory presynaptic potential

Question

Quizplus · Accepted Answer

An excitatory postsynaptic potential (EPSP) is a change in the postsynaptic membrane potential that makes the neuron more likely to fire an action potential. This is because the EPSP brings the membrane potential closer to the threshold needed to trigger an action potential.
