Figure 7. Projections of VTA NtsR1 neurons via acute projection labeling. Distribution of Ad-syn-mCherry-labeled terminals from the 7–10 D-injected mice described in Figure 6. Syn-mCherry-labeled terminals were observed in the (A) NAc, (B) NAsh, (C) OFT, (D) absence of terminals in the PFC, (E) CPu, (F) IPAC and ST, (G) VP, (H) CeA, both medial (med) and lateral (lat) portions, (I) LHb, (J) LHA, (K) LDTg, and (L) the medial and lateral portions of the PBN (medPBN and latPBN). M, Schematic summarizing projections of VTA NtsR1 neurons (purple stars). Scale bars: 100 µm. aca, anterior commissure; cc, corpus callous; BLA, basolateral amygdala; 3V, third ventricle; f, fornix; 4V, fourth ventricle; scp, superior cerebellar peduncle.
