Figure 2.

Representative vibratome sections through the vestibular nuclei from two sGVS-stimulated (A,B) and two mock (non)stimulated (C,D) rats processed for immunoperoxidase/diaminobenzidine staining of c-Fos protein. c-Fos-immunoreactive neuronal nuclei are apparent in the spinal and medial vestibular nuclei (SpVN, MVN), as well as nucleus tractus solitarius (NTS), of the stimulated animals. Sections from the mock-stimulated animals contained c-Fos-labeled cells in NTS, but rarely in the vestibular nuclei. Scale bar in (D) is for all panels.
