Several nuclei at the level of the obex are related to the vagus
nerve (Fig. 1). These nuclei, sometimes referred to as the dorsal
vagal complex (DVC), include the area postrema, dorsal motor
nucleus of the vagus (DMX), and the solitary tract (ST) with its
surrounding nuclei. The nucleus ambiguus, located in the ventrolateral
part of the tegmentum medial to the spinal trigeminus
and dorsal to the inferior olivary complex, though not part of the
DVC, is part of the vagal system in that it is the source of lower
motoneurons in the nerve.
The solitary tract is a conspicuous compact bundle surrounded
by several subnuclei which constitute the solitary complex. This
complex in cats is described by disparate investigators using different
criteria as having two nuclei referred to as the medial (Sm)
and lateral (Sl) solitary nuclei (14) five (116) six (86) and even
eight subnuclei (67). For the present purposes, the terms ventral
solitary nucleus (Sv) and subnucleus gelatinosus (Sg) will be
employed in addition to Sm and Sl. Cells of this group of nuclei
tend to be small with finely granular Nissl material. The cells of
the solitary nuclei appear rather loosely organized and difficult
to delimit. The main basis for their subdivision is geographic with
regard to the tract. It should be noted that some cells of the solitary
nuclei are quite large and may be diffusely located in all the
various subnuclei, but especially in Sl.
