Fullerenol enhanced long-term synaptic plasticity in hippocampal Sch-CA1 pathway. A The I/O curve shown as fEPSP slope, B The PPF ratio shown as fEPSP2/fEPSP1, C The LTP induction shown as fEPSP slope in percent indicated that long-term maintenance of synaptic plasticity by fullerenol was found in hippocampal CA1 area. One-way ANOVA with Tukey-test post hoc analysis was used in the peak analysis of the PPF ratio curve. Two-way ANOVA with Tukey-test post hoc analysis was for all other studies. ** P < 0.01, *** P < 0.001 compared with the control group. ^## P < 0.01, ^### P < 0.001 compared with the lead-exposed group
