The nerves innervating the sublingual gland of the rat was investigated using PRV (pseudorabies virus) as a neural tracer. The neural tracer was injected into left sublingual gland of the rat. In the central nervous system, PRV immunoreactive neurons were labeled bilaterally and tended to be more densely labeled in the left side. PRV immunoreactive neuronal cell bodies and fibers were observed in insular cortex, paraventricular nucleus, deep mesencephalic nucleus, spinal trigeminal tract, lateral paragigantocellular nucleus, parvicellular reticular nucleus, raphe obscurus, gigantocellular reticular nucleus and gigantocellular reticular nucleus, alpha. The more densely labeled PRV immunoreactive neurons were found in the deep mesencephalic nucleus, spinal trigeminal tract and lateral paragigantocellular nucleus. These results may provide a neuroanatomical data on the nerves innervating the sublingual gland in the rat brain.
