Representative photomicrographs of Fos protein expression in the IL from a rat in (A) the COC-NoA group, (B) the Sal-NoA group, (C) the COC-ISO group and (D) the Sal-ISO group in Experiment 2. Visible Fos protein expression was manifested as dark ovals (highlighted by arrows). All images were taken at 20× magnification. Scale bar is equal to 100 µm.
