TH protein decreased on average 63% following 6-OHDA lesion in striatum (n=11, *p=0.0002, t=5.76, df=10) and 52% in SN (n=11, *p=0.0015, t=4.31, df=10). There was no significant difference in TH protein loss between these two regions following medial forebrain bundle lesion with 6-OHDA (n=11, p=0.24, t=1.24, df=10).
