Post-tetanic potentiation

Post-tetanic potentiation (PTP) is a form of synaptic plasticity which is short-lived and results in increased frequency of miniature excitatory postsynaptic potentials (mEPSPs) or currents (EPSCs) with no effect on amplitude in the spontaneous postsynaptic potential. It usually lasts in the range of several minutes. PTPs are observed when synapses are stimulated with repetitive (tetanic) pulses, by means of prolonged trains of stimuli applied at high frequencies.
