FIGURE 2.
Anatomical and morphometric analyses of TH-positive cell of the VTA and SNpc catecholamine nuclei. (A) Nissl staining of the mouse brain at the Bregma level –3.02 (Paxinos and Franklin, 2001) showing the anatomical localization of the VTA and SNpc. (B,C) Representative images of TH immunoreactive cells of the VTA and SN. Images at higher magnification (100X) show the morphological features of TH-positive cells of the VTA and the dorsal (dt) and ventral (vt) tier of the SNpc. Scale bar: 100 μm for 20X and 10 μm for 100X. The corresponding morphometric analyses are shown in (D). Values are means ± SEM.
