Figure 4: VGluT2 neurons in the caudal portions of the marmoset VTA and SNC.
From: Glutamate neurons are intermixed with midbrain dopamine neurons in nonhuman primates and humans

(A) Coronal section showing TH-expression at the level of the CLi (interaural 4.0). (B-F”) Higher magnification of boxed areas in A. (B-C”) Detection of VGluT2-only and TH-only neurons in the CLi (B) and VTAC (C). (D) Frequent detection of dual VGluT2-TH neurons (red arrows) in the caudal PBP. (E) Detection of VGluT2-only neurons and TH-only neurons in the SNCl. (F) Lack of detection of VGluT2 neurons within the SNCv. Scale bar in A = 250 μm, scale bar in B = 25 μm and applies to B-B”, C-C”, D-D”, E-E”, and F-F”.
