A The changes of senile plaques (SPs) in the hippocampus. B The changes of SPs in the mice cortex. The stained SPs were indicated by the black arrow, a,e: the control group, b,f: the model group, c,g: the 2 periods of EA treatment group, d,h: the 3 periods of EA treatment group. C The number of staining for SPs in the hippocampus of each group. ****p < 0.0001 versus the control group, ##p < 0.01 and ####p < 0.0001 versus the model group, ΔΔP < 0.01 versus the 2 periods of EA treatment group. D The number of staining for SPs in the cortex of each group. ****p < 0.0001 versus the control group, ###p < 0.001 versus the model group (n = 6 in each group).
