Effects of acupuncture stimulation on MPTP-induced dopaminergic neuronal death in the substantia nigra (SN) and the striatum (ST). MPTP administration induced dopaminergic neuronal death, whereas acupuncture stimulation at GB34 prevented it. Scale bar 200 µm. Data are shown as the means ± the standard errors of means. **p < 0.01 and ***p < 0.001 versus the saline group and ^# p < 0.05 versus the MPTP group and ^† p < 0.05 versus the MPTP + SI3 group
