Figure 1

Brain sectioning. H0: the horizontal zero plane. A35, A25, A20, A15, A10, A5, and 0 show transverse planes at 35, 30, 25, 20, 15, 10, 5, and 0 mm rostral to the interaural line, and P5, P10, P15, and P20 show transverse planes at 5, 10, 15, and 20 mm caudal to the interaural line, respectively. The locations of nuclei or areas in the brain blocks are presented at the top of the figure. The nuclei and areas identified include the nucleus accumbens (ACB), the septal area (SA), the caudate nucleus (CAU), the supraoptic nucleus (SON), the paraventricular nucleus of the hypothalamus (PVH), the ventromedial nucleus of the hypothalamus (VMH), the arcuate nucleus (ARC), the amygdala (AMY), the habenular nucleus (HB), the periaqueductal grey (PAG), the substantia nigra (SN), the parabrachial nucleus (PBN), the locus coeruleus (LC), the nucleus raphe magnus (NRM), the gigantocellular reticular nucleus (GI), and the nucleus tractus solitarius (STN). The symbols in Figure 2 and Table 1 have the same meanings.
