Fig. 5From: Sex differences in spatial learning and memory and hippocampal long-term potentiation at perforant pathway-dentate gyrus (PP-DG) synapses in Wistar ratsTime-dependent variations in hippocampal evoked responses to PP stimulation following an HFS. Upper panel shows representative traces of evoked field potential recording in the DG area prior to and 60 min after HFS. Male rats exhibited significantly more fEPSP slope LTP than females. Left lower panel shows fEPSP slope change (%) vs. time following HFS in both sex of rats. Bar graphs show the average fEPSP slope change (%) during 60 min post-HFS. Data are expressed as means ± SEM % of baseline. *P < 0.05Back to article page
