Figure 6.

Extended amygdala and basal amygdala afferents to VTA. VTA-projecting neurons in dorsal and ventral BNST, SLEA, and AA expressed Fos in relation to behavior. BNST and SLEA projections expressed the most Fos in reinstatement animals, whereas AA efferents were activated in both reinstatement and locomotor control groups. No differences between behavioral groups were seen in IPAC, MeA (medial amygdala), CeA, or BLA. *p < 0.05, **p < 0.01: CS+ vs all controls (Ext, CS−, Loco); ⁺p < 0.05, CS+ vs Ext, CS− only. Error bars indicate SEM.
