Expression of vesicular glutamate transporters in peripheral vestibular structures and vestibular nuclear complex of rat

▶VGLUT1 and VGLUT2 define three subsets of Scarpa's ganglionic neurons. ▶Vestibular primary afferents use VGLUT1/VGLUT2 to load glutamate at axon terminals. ▶Vestibular hair cells use VGLUT3 to load glutamate. ▶More vestibular nulcear neurons express VGLUT2 mRNA than VGLUT1 mRNA.
