Fig. 6.

Number of PVT neurons immunolabeled for cFos following the social approach-avoidance test. (A) The number of cFos positive nuclei per mm² in the anterior (aPVT) and posterior PVT (pPVT) in saline treated rats expressing hM4Di. (B) Number of cFos positive nuclei per mm² in the PVT. (C) Percentages of PVT neurons double-labeled for cFos and mCherry. (D) Representative images of the PVT showing mCherry + neurons, cFos + neurons, and double-labeled cFos+/mCherry + neurons in an hM4Di + Sal and an hM4Di + Clz case. Data are means ± SEM. *p < 0.05, **p < 0.01, ***p < 0.001. Group size n = 4 cases for each bar. Scale bar, 50 μm.
