The solitary tract (tractus solitarius or fasciculus solitarius) is a compact fiber bundle that extends longitudinally through the posterolateral region of the medulla oblongata. The solitary tract is surrounded by the solitary nucleus , and descends to the upper cervical segments of the spinal cord .
The solitary nucleus (SN) (nucleus of the solitary tract, nucleus solitarius, or nucleus tractus solitarii) is a series of neurons whose cell bodies form a roughly vertical column of grey matter in the medulla oblongata of the brainstem. Their axons form the bulk of the enclosed solitary tract. The solitary nucleus can be divided into different ...
To produce the sense of taste, these neurons project to the gustatory nucleus, or the rostral and lateral regions of the nucleus of the solitary tract, and are ultimately projected to the cerebral cortex. [3] The tongue contains taste receptors, that sends sensory information via action potential to the solitary nucleus.

Near the sulcus limitans are the visceral afferent nuclei, namely the solitary tract nucleus. More lateral, but also less posterior, are the general somatic afferent nuclei. This is the trigeminal nucleus. Back at the dorsal surface of the brainstem, and more lateral are the special somatic afferents, this handles sensation such as balance.

The area postrema connects to the solitary nucleus, or nucleus tractus solitarii (NTS), and other autonomic control centers in the brainstem.It is excited by visceral afferent impulses (sympathetic and vagal) arising from the gastrointestinal tract and other peripheral trigger zones, and by humoral factors.
