The number of FOS-expressing neurons is up-regulated within IC in CP rats. a-c: Immunochemical staining of FOS within different coronal sections of IC in sham (left) and CP rats on POD 14 (right). Bar = 200 μm. d: Histogram showing the qualification of FOS-expressing neurons within different parts of IC in saline or TNBS-treated rats. n = 3 slices from 3 rats in each group, unpaired t-test, * P < 0.05, ** P < 0.01, TNBS vs sham
