Photomicrographs of α-syn and TH immunostaining in the nigrostriatal dopamine system and forebrain structures at 31 years of age.

<p>A: α-Syn-positive neurons in the medial part of the SNc (mSNc). B: α-Syn-positive neurons in the lateral part of the SNc (lSNc). C: TH-positive neurons in the mSNc. D: TH-positive neurons in the lSNc. E: TH-positive fibers and terminals in the rostral aspect of the putamen (rPut). F: TH-positive fibers and terminals in the caudal aspect of the putamen (cPut). G: Phosphorylated α-Syn immunostaining in the lSNc. G: Phosphorylated α-Syn immunostaining in the amygdala (Amy). Scale bars, 50 μm.
