Ferret exposure increased the number of Fos-positive cells in the MeA, CeA and BLA. Immunohistochemistry with an antibody directed against Fos was performed on brains obtained for the same rats that were used for the corticosterone measurements in Fig. 2. (A) The number of Fos-positive cells present per mm2 in the indicated brain region from rats that were sacrificed at various time points after a 10 min exposure to the ferret; control rats remained in their home cages until time of sacrifice. Ferret exposure produced a time-dependent increase in the number of Fos-positive cells/mm2 in each of the brain regions examined. Bars represent the mean+SEM for each group from 8 independent determinations, *p<0.05, **p<0.01, ***p<0.001 compared to Control. (B) Images of the amygdala region from a control and a ferret-exposed rat sacrificed 60 min following ferret exposure. The following regions are identified on the figure: MeA, medial amygdala; CeA, central amygdala; BLA, basolateral amygdala; opt, optic tract; cst, commissural stria terminalis. Scale bar = 500 microns.
