对8只雄性恒河猴在单独笼和群笼中进行了为期9个月的研究。在此期间，对组中最占优势的3只动物进行双侧杏仁核切除术。发现手术前个体笼中的攻击性与组笼情况中的优势之间存在负相关。杏仁核切除术后，所有动物在单独笼内的情况下表现出更强的攻击性。在组笼情况下，相同动物在2/3例中从层级中的顶部位置下降到底部位置。3d动物的优势没有丧失，并且在手术后的组情境中表现出更强的攻击性。行为变化的差异似乎与每只动物在手术后返回该组时所面临的社会环境以及术前关系存在的时间长度有关。行为变化的差异与整体病变程度的差异无关，尽管它们与杏仁核基底外侧核损伤的差异一致。
Eight young male rhesus monkeys were studied in individual and group cages for a period of 9 mos.; during this time, the 3 animals that were most dominant in the group situation were subjected to bilateral amygdalectomy. There was found to be a negative relationship between aggressiveness in the individual-cage and dominance in the group-cage situation before surgery. After amygdalectomy all animals appeared more aggressive in the individaul-cage situation. In the group-cage situation, the same animals, in 2 of 3 instances, fell from top to bottom positions in the hierarchy. The 3d animal suffered no loss in dominance and appeared more aggressive in the group situation after operation. The differences in changes in behavior appeared to be related to the social environment confronting each animal upon returnrto the group after surgery and to the length of time the preoperative relationships had existed. The differences in changes in behavior are not related to the differences in extent of lesions as a whole, though they are consistent with differences in damage to the basolateral nuclei of the amygdala.
