In the preoptic regions, relatively sparse numbers of marked cells were observed in the median preoptic, anteroventral periventricular, medial preoptic, anterodorsal preoptic, anteroventral preoptic, and parastrial nuclei, as well as in the undifferentiated part of the medial preoptic area. In addition, a very few retrogradely labeled neurons were noted in the lateral preoptic area (Fig. 3C-F).

At the anterior hypothalamic level, ascending fibers coursing through the hypothalamus supply dense inputs to the anterior hypothalamic nucleus, subparaventricular zone, rostral retrochiasmatic area, and perifornical region of the lateral hypothalamic area in addition to a relatively sparse input to the other regions of the lateral hypothalamic area (Figs. 5D–G, 6B).
