参与该研究的志愿者年龄介于19岁到83岁之间，研究者请他们填写调查问卷，以得出他们经常联系的朋友个数以及有多少种不同类别的朋友。 磁共振成像扫描显示，杏仁核的大小与社交生活的丰富程度成正比。美国东北大学的心理学家丽莎 贝瑞特教授在《自然神经科学》杂志上发表了以上调查结果。东北大学位于马萨诸塞州波士顿市。 贝瑞特教授说调查结果与社会脑理论相符，该理论认为人类杏仁核的进化是为了应对愈来愈复杂的社交世界。 其他对灵长类动物的研究发现，群居动物的杏仁核要更大一些。这些研究成果发表在《自然神经科学》的一项新研究报告中。 东北大学的心理学教授丽莎 贝瑞特博士参与了这项课题，她说人类的杏仁核变大是为了应付日益繁忙的社交生活。 她接着说：我们目前正在进行更深层次的研究，来进一步了解杏仁核和其他脑部区域如何影响人类的社会行为。 她的同事布拉德福德 狄克生博士说：我们观察了人们的杏仁核大小与社交圈大小和复杂程度之间的关系。我们的观察对象有老有少，有男有女。狄克生博士是哈佛大学医学院的神经病学副教授。 美国科学家们观察了一位因病导致杏仁核受损的妇女，最近他们就观察结果作了报告。 报告显示，这位已经是三个孩子母亲的44岁的女人从来感觉不到恐惧，并经常将自己置于危险的境地。这些年来，她遭受过匕首威胁，被人拿枪指过头，还曾经惨遭殴打。</p>
