Tail vein injection of LiCl induces no obvious Fos expression. a Quantification of Fos-like immunoreactivity in the aIC, the mIC, and the pIC after intraperitoneal injection of Saline or LiCl (15 mg/kg) (n = 10 mice per group, F (2, 57) = 1.694, P = 0.193, Data are presented as means ± SEM). b, c Representative histology (b) and quantification (c) of Fos-like immunoreactivity in the left- and right-side of the aIC, the mIC, the pIC, the PVT, the CeA, and the PBN. Data were presented as means ± SEM, Scale bar, 100 μm
