TNBS treatment increases the number of FOS-ir neurons in the NTS and ACC. AJ Immunochemical staining of FOS in the NTS (AE) and ACC (FJ) in sham rats on POD 14 and in TNBS-treated rats on POD 3, 7, 14, and 28 (scale bars, 200 μm). K, L Numbers of FOS-ir neurons in the NTS (K) and ACC (L) in sham rats on POD 14 and in TNBS-treated rats on POD 3, 7, 14, and 28. M Numbers of FOS-ir neurons in different layers of the ACC in sham rats and TNBS-treated rats on POD 14 (n = 3 per group; *P < 0.05, **P < 0.01, *** P < 0.001, TNBS vs sham, one-way ANOVA in K, L, unpaired t-test in M.
