WebAug 10, 2011 · nucleus tractus solitarius(NTS), a structure located in the dorsomedial portion of the caudal medulla, receives visceral afferent inputs from throughout the body and relays these signals to regions of the central nervous system that regulate autonomic functions (18, 28, 29). WebA denser terminal field is found in the Ad2 adrenergic group of neurons situated midway between the solitary tract and the area postrema. A dense terminal field of fibers from the area postrema also surrounds the NA2 noradrenergic group ( Cunningham et al., 1994 ).
