Cranial nerves3
Through the center of the SN runs the solitary tract, a white bundle of nerve fibers, including fibers from the cranial nerves VII, IX, and X. Cell bodies of the SN are roughly somatotopically arranged along its length according to function: for instance, cells involved in taste are located in the rostral part, while those receiving information from cardio-respiratory and gastrointestinal processes are found in the caudal part.
