Question

Quizplus · Accepted Answer

EPSPs (excitatory post-synaptic potentials) increase the likelihood of firing by depolarizing the neuron and bringing it closer to threshold. IPSPs (inhibitory post-synaptic potentials) decrease the likelihood of firing by hyperpolarizing the neuron and moving it further from threshold. Therefore, EPSPs increase the rate of firing, while IPSPs decrease it.
