High-frequency presynaptic stimulation fails to induce LTP. A, Control unitary EPSPs were obtained by paired recording from a Dep MN (top trace, superimposed raw data; middle trace, average) and a presynaptic CBT (bottom trace, average from 25 consecutive raw data). The histogram displays the distribution (number of occurrences) of EPSP amplitudes. B, Induction protocol. The CBT was high-frequency-stimulated while the Dep MN remained silent.Depn and CBn, Extracellular neurograms of Dep motor nerve and CBCO sensory nerve, respectively; Dep MN and CBT, paired intracellular recordings from a Dep MN and a CBT. C, After application of the induction protocol, no changes were observed in a single monosynaptic EPSP (same arrangements as in A).
