Nucleus of the solitary tract

The solitary nucleus and tract are structures in the brainstem. The solitary tract nucleus consists of bilateral columns of neurons that extend from near the spinal cord. The solitary tract nucleus receives information directly from primary afferent neurons located in the peripheral nervous system and convey chiefly information from visceral organs like the heart, lungs and gastrointestinal system as well as gustatory information from the oral and nasal cavities.
