Hippocampus synaptic plasticity among the 4 groups. a Camera tracings of hippocampal CA1 neurons among the different groups. b Sample images of Golgi-Cox staining of CA1 neurons for spine counting. c Representative dendritic spine density of hippocampal CA1 neurons. d Quantitation of the dendritic intersections. e Quantitation of the total dendritic length. f Quantitation of the dendritic spine density. g LTP recording in the hippocampal CA1 region. Arrows indicate the time point of TBS application. h Averaged fEPSP slope during the last 20 min. The data are presented as the means ± standard error of the mean for each group (n = 6). *p < 0.05, **p < 0.01 compared with the C + VEH group, ^#p < 0.05 compared with the A/S + VEH group. Scale bar = 10 μm
