Long-term potentiation of EPSCs. a Responses of cerebellar nuclear neurons to three induction protocols, consisting of a 250 ms train of EPSPs at 133 Hz, applied during the colored bar and a 150-ms hyperpolarization. b Left EPSCs evoked at –65 mV before and after 30 applications of the induction protocol. Right Efficacy of the various induction protocols in inducing long-term potentiation of EPSCs, plotted as the percent change in EPSC amplitude, against the onset of the excitatory synaptic stimulation relative to the time of disinhibition. Bars indicate the duration of the EPSPs. Data from [38], reproduced with permission
