Differential synaptic LTP response to high-frequency stimulation in LE and SD rats. (a) Average input/output curves between stimulation voltage and fEPSP slope show no significant difference in basal synaptic excitability. (b) LTP responses to the 50/50 HFS protocol in LE rats (black, n = 11) were significantly higher than in SD rats (green, n = 8) through the whole 2-hour posttetanisation. Data are presented as means ± 95%confidenceintervals. Outsets above the LTP curve represent average waveform field potentials during 30 min baseline prior to tetanisation and 0-30 min and 90-120 min posttetanisation. Horizontal bar: 1 mV; vertical bar: 5 ms. (c) PTP, STP, and LTP responses are presented as means ± 95%confidenceintervals; ∗∗pvalue < 0.01 and ∗∗∗pvalue < 0.001).
