Figure 4. TH immunostaining in the substantia nigra pars compacta (SNc), and the ratio to the intact side.
(A) TH immunostaining in the intact SNc. Severe loss of TH-positive neurons was seen in the lesioned side SNc of control group. Preservation of TH-positive neurons was seen at the lesioned side SNc of 50 Hz SCS group. Scale bar: 200 µm. (B) Significant preservation of TH-positive neurons in the lesioned-side SNc of 50 Hz SCS group, compared to those of control group (*p<0.05, n = 10, respectively).
