Anatomy of the nodose ganglion in the rat: central projections of afferent fibers in the hepatic vagus.

Horseradish peroxidase (HRP) was applied to the rostral end of sectioned hepatic vagi (HV) . Subsequently, a count of HRP—labeled cells in the nodose ganglia (NDG) yielded an estimate of the minimum number of afferent fibers in the HV of 139. HHP labeled cells were found only in the left NDG and were diffusely spread throughout the ganglia. No HRP labeling was found in areas of the brain previously reported to contain vagal afferent projections. In three cases small numbers of HRP labeled cell bodies were seen in the dorsal motor nucleus (DMN) . The NDG were organized with cell bodies on the sides and their processes and fibers of passage in the center. The NDG have an apparent population of two cell types; large sensory neurons and smaller glial cells. However, the possibility of a population of smaller sensory cells is discussed. An average of total sensory cell counts for three NDG yielded an estimate of 9115 sensory cells.
