FIGURE 2.

Darkfield photomicrographs illustrating the distribution of PHAL axons from the dorsomedial BNST in the pv (a, b), in the PVH (a–c), in the VMH (d–f), in the LHA (d–f), in the ARH (d, e) and in the tuberal nucleus (d, e). These areas receive light (anterior hypothalamic nucleus, AHN), moderate (PVH) to intense (LHA) innervation from the anterior divisions of the bed nucleus of the stria terminalis. Three experiments are illustrated: Experiment BNST#6 (a, b, d), experiment BNST#1 (c) and experiment BNST#4 (e, f). ARH, arcuate nucleus of the hypothalamus; cp, cerebral peduncle; DMH, dorsomedial nucleus of the hypothalamus; fx, fornix; LHA, lateral hypothalamic area; pv, periventricular nucleus; PVH, paraventricular nucleus of the hypothalamus; TU, tuberal nucleus; VMH, ventromedial nucleus of the hypothalamus; V3, third ventricle; ZI, zona incerta. Scale bars are shown in the figure [Color figure can be viewed at wileyonlinelibrary.com]
