Serotonergic effectors of mesolimbic dopamine neurons. A, Coronal section showing Bregma −4.72 (Franklin and Paxinos, 2008) and section of infected CNS tissue indicating the dorsomedial, ventromedial, and dorsolateral wings of the dorsal raphe. The section is stained with anti-Tph2, anti-GFP, and DAPI. B, High-magnification images of DRL/DRD and DRV. C, Percent colocalization (ratio of the number of cells in the DRN stained with both Tph2 and GFP to the number stained with Tph2 only). Error bars indicate SEM. D, Quantification of cells in the DRN stained with Tph2 only, GFP only, or both Tph2 and GFP. Scale bars: A, 250 μm; B, 100 μm.
