Quizplus · Accepted Answer

An excitatory postsynaptic potential (EPSP) is a synaptic potential that makes a neuron more likely to fire an action potential. This is typically achieved by the neurotransmitter-induced depolarization of the postsynaptic membrane, making the neuron's internal environment less negative and closer to the threshold for firing an action potential.
