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 ).
WebThe AP along with the nucleus of the solitary tract (NTS) and the dorsal motor nucleus of the vagus makes up the so-called dorsal vagal complex, which is the major termination site of vagal afferent nerve fibers.
