The medial nucleus of the amygdala (Me), bed nucleus of the stria terminalis (BNST), and medial preoptic area (MPOA) regulate copulation in the male hamster. The present study identified neuropeptide Y-immunoreactive (NPY-IR) neurons in the BNST and Me with the greatest concentration in the posteromedial and posteriordorsal subdivisions of these nuclei, respectively. NPY-IR filters are found in all three nuclei with dense plexi of NPY-IR varicosities in the most medial subdivisions. Substance P neurons are also densely concentrated in the posterior BNST and Me; however, no neurons contained both peptides. Thus, NPY and substance P neurons comprise two distinct populations within the BNST and Me of the hamster.
杏仁核内侧核（Me）、终纹床核（BNST）和内侧视前区（MPOA）调节雄性仓鼠的交配行为。本研究在BNST和Me中鉴定出神经肽Y免疫反应性（NPY-IR）神经元，这些神经元分别在这些核的后内侧和后背部亚区中浓度最高。在所有这三个核中均发现了NPY-IR纤维，在最内侧亚区有密集的NPY-IR曲张体丛。P物质神经元也密集地集中在BNST后部和Me中；然而，没有神经元同时包含这两种肽。因此，NPY和P物质神经元在仓鼠的BNST和Me中构成两个不同的群体。
