(A) Schematic coronal slice indicating the region where the counting was done in different areas: IL cortex (A1), VTA (A2). (B) Photomicrographs 100x magnification: IL cortex (B1) and VTA (B2). Photomicrographs 200x magnification of the pattern of Fos-IR neurons in IL cortex or Fos/TH-IR neurons in VTA after an amphetamine challenge in (C) veh-sal group in different areas: IL cortex (C1), VTA (C2); (D) veh-amph group in IL cortex (D1), VTA (D2); (E) cv-sal group in IL cortex (E1), VTA (E2); and (F) cv-amph group in IL cortex (F1), VTA (F2). A section of each photomicrographs of Fos/TH-IR (indicated by a square) is shown in a higher magnification (1,000x). Scale bar = 100 μm.
