Sodium channels Nav1.6 and Nav1.7 expression in rat glomerular layer of olfactory bulb. Immunolabeling experiments show that the synaptophysin-positive (green) glomeruli of the olfactory bulb exhibit extremely limited Nav1.7 (red) immunoreactivity. In contrast, Nav1.6 (red) exhibits robust immunoreactivity within the synptophysin-positive (green) glomeruli of the olfactory bulb.
