The nucleus of the solitary tract consists of a set of nuclei in medulla oblongata involved in several homeostatic systems. No method has been proposed so far to image it in vivo, due to its low contrast with standard T1 and T2-weighted methods, its small size and its position deep in the medulla. In this study we present preliminary results that indicate that NTS may be sensitive to magnetization transfer effects.
