Figure 2

Photomicrographs of H129 labeling in the brainstem of a male (left) and female (right) rat, as a result of genital inoculation. Note the robust labeling within the rostroventrolateral medulla in both sexes, and more dorsal brainstem regions in males. Discrete labeling within the nPGi was observed in both sexes. 4v = 4th ventricle, nPGi = nucleus paragigantocellularis, py = pyramidal tract.
