Fig. 4From: Synaptic plasticity in hippocampal CA1 neurons and learning behavior in acute kidney injury, and estradiol replacement in ovariectomized ratsa Paired-pulse facilitation induction of fEPSPs recorded in the CA1 area after stimulation of Schaffer collaterals. The percentages denote the ratio of the second fEPSP slope to the first fEPSP slope. PPR (facilitation or depression) was tested at 10, 20, 30, 50, 70, 150, 300, 500 and 1000 ms IPIs between groups. Data are expressed as mean ± SEM (n = 10). **P < 0.01 IRI-E versus IRI-veh at the IPI 300. b Representative sample paired-pulse traces in experimental groupsBack to article page
