A schematic representation of the distribution of c-Fos-positive cells in the vestibular nuclear complex of one rat following sGVS (see Materials and Methods for details) is shown on the left side of the atlas sections (modified from Paxinos and Watson, 1998). The highest overall density of immunostained neurons was present in the medial vestibular nucleus (MVN). These cells were localized almost exclusively in the parvocellular region (MVNpc) and caudal MVN. Immunopositive neurons were present throughout the caudal half of the spinal vestibular nucleus (SpVN), and there was a small dense cluster of immunopositive neurons in the superior vestibular nucleus (SVN). Only labeling in the vestibular nuclei is plotted on this schematic. Approximate Bregma coordinates from the published atlas are indicated to the left.
