Photomicrographs of the medial prefrontal cortex (A-D), PVN (E-H), and the amygdala (I-L) showing increase in c-Fos-immunoreactive cells in response to C. jejuni challenge as well as holeboard exposure. For each brain region, the four panels depict each of the four experimental conditions indicated in the bottom left of the panels. Inserts depicting diagrams of brain sections show the locations of the photomicrographs (modified after Paxinos and Franklin, 2001). Abbreviations: 3V: third ventricle; ac: anterior commisure; ACC: anterior cingulate cortex; AHA: anterior hypothalamic area; BLA: basolateral nucleus of the amygdala; BST: bed nucleus of the stria terminalis; CEA: central nucleus of the amygdala; f: fornix; ILC: infralimbic cortex; LA: lateral nucleus of the amygdala; LV: lateral ventricle; PLC: prelimbic cortex; PVN: paraventricular nucleus of the hypothalamus. Scale bars in A, E, I: 250 μm, and apply to other corresponding panels.
