情绪记忆的神经生物学解释主要来自动物模型，这些动物模型研究了威胁信号事件的记忆编码和保留。这篇文献暗示杏仁核，大脑颞叶的一个结构，在学习和巩固恐惧记忆。它在恐惧条件反射中的作用已经得到证实，但人类杏仁核也与皮质区域相互作用，以调节情绪记忆的其他方面。这些包括编码和巩固愉快和不愉快的唤醒事件到长期记忆，集中在中央情绪信息的缩小，检索先前的情绪事件和上下文，以及在检索过程中的回忆和情绪强度的主观体验。沿着其他不涉及杏仁核的机制，这些功能确保重要的生活事件在记忆中留下持久的印象。
Neurobiological accounts of emotional memory have been derived largely from animal models investigating the encoding and retention of memories for events that signal threat. This literature has implicated the amygdala, a structure in the brain's temporal lobe, in the learning and consolidation of fear memories. Its role in fear conditioning has been confirmed, but the human amygdala also interacts with cortical regions to mediate other aspects of emotional memory. These include the encoding and consolidation of pleasant and unpleasant arousing events into long-term memory, the narrowing of focus on central emotional information, the retrieval of prior emotional events and contexts, and the subjective experience of recollection and emotional intensity during retrieval. Along with other mechanisms that do not involve the amygdala, these functions ensure that significant life events leave a lasting impression in memory.
