Fig. 6From: 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. Male rats exhibited significantly more PS amplitude LTP than females. Left panel shows PS amplitude change (%) vs. time following HFS in both sex of rats. Bar graphs show the average PS amplitude change (%) during 60 min post-HFS. Data are expressed as means ± SEM % of baseline. *P < 0.0001Back to article page
