This image shows dorsal root ganglion sensory neurons of the vesicular glutamate transporter 3 (Vglut3) lineage (red). Neurons are also labeled with antibodies against βIII-tubulin (green) and neurofilament heavy chain (blue). Mentholsensitive Vglut3-lineage neurons are a highly excitable population that fire robust trains of tetrodotoxin-sensitive action potentials and show unique sodium channel inactivation kinetics. For more information, see the article by Griffith et al. (pages 7086–7101).
