本研究在非繁殖季节对笼养雄性鸣禽（Melospiza melodia）进行了研究，目的是（1）检测基底前脑部位对模拟领土入侵的Fos和Zenk反应，（2）确定这些反应与攻击的关系。许多前脑区表现出显着的Fos和Zenk响应模拟领土入侵，并在几个地区的下丘脑和外侧隔，这些反应与攻击行为呈负相关。在哺乳动物中，从属受试者的同源性区域比主导受试者的反应更大。因此，这些大脑区域可能会对各种脊椎动物的社会压力做出反应。
The present study was conducted on captive male song sparrows (Melospiza melodia) during the nonbreeding season in order to (1) examine Fos and Zenk responses of basal forebrain sites to simulated territorial intrusion and (2) determine how those responses relate to aggression. Numerous forebrain areas showed significant Fos and Zenk responses to simulated territorial intrusion, and in several areas of the hypothalamus and lateral septum, these responses were negatively correlated with aggressive behavior. Homologous areas in mammals show greater responses in subordinate subjects than in dominant subjects. Thus, these brain areas may be responsive to social stressors across a wide range of vertebrates.
