WebIn the human brainstem, the solitary nucleus, also called nucleus of the solitary tract, nucleus solitarius, and nucleus tractus solitarii, (SN or NTS) is a series of purely sensory nuclei (clusters of nerve cell bodies) forming a vertical column of grey matter embedded in the medulla oblongata. The area postrema was first named and located in the gross anatomy of the brain by Magnus Gustaf Retzius, a Swedish anatomist, anthropologist and professor of histology. In 1896, he published a two-volume monograph on the gross anatomy of the human brain in which the area postrema was mentioned.
