EPSPs (excitatory postsynaptic potentials) do not have a refractory period. This term is typically used to describe the period of time after an action potential during which a neuron is unable to fire another action potential. EPSPs are graded responses initiated by neurotransmitters that can summate to reach the threshold for an action potential, but they themselves do not have a refractory period.
