Rostral nucleus solitarius
Solitary nucleus, also called nucleus of the solitary tract (SN or NTS) is a series of purely sensory nuclei forming a vertical column of grey matter embedded in the dorsolateral medulla.

The SN projects to, among other regions, the reticular formation, parasympathetic preganglionic neurons, hypothalamus and thalamus, forming circuits that contribute to autonomic regulation.
