Figure 4

(A) Schematic showing regions analyzed using fluorescent immunohistochemistry (Paxinos & Watson 2005). Representative images: (B) Fos+Arc double-labeling in dmPFC, scale bar 50μm; Arc-labeling in red, Fos-labeling in green, examples of double-labeled neurons in red and green indicated by white arrows. (C) Fos+NPY double-labeling in OFC, scale bar 50μm; NPY-labeling in green, Fos-labeling in red, example of double-labeled neuron in red and green indicated by white arrow.
