Description of part

The most prominent component of the posterior division is a large, sausage-shaped nucleus, which may correspond to the encapsulated nucleus referred to but not illustrated by Young (’36) in the rabbit (also see Simerly and Swanson, ’86). The region that we refer to specifically consists of densely packed, small, round to oval-shaped neurons (Figs. 30, 31). Rostrally, it lies just ventral to the tip of the lateral ventricle (Fig. 5), whereas at more caudal levels it spreads ventrally and medially, and its caudal tip comes to lie just beneath the descending column of the fornix (Fig. 8). Caudal parts of the posterodorsal (preoptic) nucleus abut the ventral and caudal border of the principal nucleus, although cells in the latter tend to be distinctly smaller than those in the posterodorsal nucleus.
