  • Values are percentages of total VGLUT3 mRNA-positive, VTA-projecting neurons and are listed in descending order; n = 5 rats (86, 87, 119, 145, and 163 double-labeled neurons per series of sections, respectively, were plotted). n.d., Not determined.

  • aIncludes the anterior nucleus of the medial bed nucleus of the stria terminalis, lateral habenula, and pontine central gray.
