Representative photomicrographs of c-Fos activity within the parabrachial nucleus (PBN) after saline (A) or lithium chloride (LiCl) injection (B) and the central nucleus of the amygdala (CNA) after a saline (C) or lithium chloride (D) injection. All nuclei in the LiCl condition showed significant elevations in c-fos expression compared to the Saline control condition. Abbreviations: basolateral nucleus of the amygdala, BLA; central nucleus of the amygdala, CNA; lateral parabrachial nucleus, LPB; medial parabrachial nucleus, MPB; optic tract, opt; superior cerebellar peduncle, scp
