Horseradish peroxidase (HRP) anterograde labeling in vestibular complex and prepositus hypoglossi in macaque monkey. (A) Schematic representation of the location of the HRP injection site in the parieto-temporal cortex. (B,C) Reconstruction of the labeled zones in the vestibular complex and in the prepositus hypoglossi. In the bottom part, darkfield photomicrographs display bright labeled neurons and fibers in the medial (M) and superior (S) vestibular nuclei and in the prepositus hypoglosi nucleus (PH). Insets are showing the locations in the brainstem where the photomicrographs have been taken. Adapted from Ventre and Faugier-Grimaud (1988).
