The anterior part of the ventromedial nucleus is moderately innervated, whereas the central part is lightly innervated, and only a few isolated fibers are observed in the ventrolateral part (Fig. 3G,H). In experiments with larger injection sites, significantly denser terminal fields in the anterior and central parts of the ventromedial nucleus are observed (Fig. 4). Interestingly, labeled fibers are never observed in the dorsomedial part of the ventromedial nucleus (or in the prominent, overlying dorsomedial nucleus of the periventricular region).

In experiments with larger injection sites, significantly denser terminal fields in the anterior and central parts of the ventromedial nucleus are observed (Fig. 4).
