Tyrosin Hydroxylase (TH) immunostaining in the striatum and substantia nigra at 1 week (Wk) and 4 weeks (Wks) post lesion. There is no significant differences in TH immunoreactivity in the striatum (A,G) and substantia nigra (C,D,I,J) of rats in the exercise group, compared to that of rats in the non-exercise group ((B,H): striatum; (E,F,K,L): substantia nigra). The optical density of striatum (M) and DA neurons of SN (N) are quantified and shown on the right. Scale bar, 2 mm (A,B,G,H); 1 mm (C–F,I–L).
