Data are presented as means ± SEM. Quantitative analysis at three levels of the VTA (rostral, medial and caudal) was conducted to determine the rostro-caudal density of neurons expressing VGluT2 mRNA or TH mRNA within the different subregions of the VTA (ventral tegmental area rostral, parabrachial pigmental area, parainterfasicular nucleus and paranigral nucleus). Density of cells expressing VGluT2 mRNA and density of cells expressing TH mRNA were calculated at the

medial (nine sections, five rats) and

caudal (four sections, three rats) levels of the VTA. Rostral VTA, −4.68 mm to −5.15 mm from Bregma; medial VTA, −5.16 mm to −5.51 mm from Bregma; caudal, −5.52 mm to −5.75 mm from Bregma.
