solitary nucleus

a collection of neural cell bodies in the medulla oblongata of the brainstem that relays information from the intermediate nerve (see greater superficial petrosal nerve), glossopharyngeal nerve, and vagus nerve. Gustatory (taste) neurons project to the anterior division of the nucleus, with touch and temperature afferents immediately lateral and visceral afferents medial and caudal. Gustatory neurons project from the solitary nucleus to control reflexes of acceptance or rejection, to anticipate digestive processes, and to activate higher levels of the taste system (see thalamic taste area). Also called nucleus of the solitary tract (NST).
