杏仁核最近受到神经科学家的密切关注，他们在分子、细胞、系统、认知和临床水平上研究杏仁核的功能。它显然有助于处理情感和社会相关信息，但一直缺乏统一的描述和计算帐户。将各种研究联系在一起的困难部分源于研究方法和物种的多样性，部分来自杏仁核在其组成核方面的固有异质性，部分原因是不同的研究者对不同的主题感兴趣。然而，一个综合现在似乎近在咫尺，从社会神经科学的新结果与神经经济学和奖励学习的数据相结合。杏仁核处理与显著性或相关性有关的心理刺激维度;已经确定了将其与处理不可预测性联系起来的机制;奖励学习的见解将其置于包括前额叶皮层和腹侧纹状体在内的结构网络中，以处理刺激的当前值。这些方面有助于阐明杏仁核的贡献，从面孔识别情绪，对同类的社会行为，并奖励学习和工具性行为。
The amygdala has received intense recent attention from neuroscientists investigating its function at the molecular, cellular, systems, cognitive, and clinical level. It clearly contributes to processing emotionally and socially relevant information, yet a unifying description and computational account have been lacking. The difficulty of tying together the various studies stems in part from the sheer diversity of approaches and species studied, in part from the amygdala's inherent heterogeneity in terms of its component nuclei, and in part because different investigators have simply been interested in different topics. Yet, a synthesis now seems close at hand in combining new results from social neuroscience with data from neuroeconomics and reward learning. The amygdala processes a psychological stimulus dimension related to saliency or relevance; mechanisms have been identified to link it to processing unpredictability; and insights from reward learning have situated it within a network of structures that include the prefrontal cortex and the ventral striatum in processing the current value of stimuli. These aspects help to clarify the amygdala's contributions to recognizing emotion from faces, to social behavior toward conspecifics, and to reward learning and instrumental behavior.
