摘　　要：一生中大多数事情会被遗忘,情绪激发能够提高记忆的储存,从而有助于人们选择性地建立起对重要经历的持久记忆。神经系统介导的情绪激发和记忆有着非常紧密的联系。情绪激发时所释放的肾上腺素和皮质酮可调节长时程记忆的巩固,杏仁核在调节这些应激激素对机体的影响中起到关键作用。应激引起的杏仁核激活以及它与其他处理记忆的相关脑区相互作用是确保具有情感意义的经历被牢记的关键。Most of our experiences will be forgotten; emotional arousal enhances the storage of memories and can serve to create, selectively, lasting memories of our important experiences. The neural system mediated emotional arousal and memory are very closely linked. The stress hormones epinephrine and corticosterone released by emotional arousal regulate long-term memory. The amygdala plays a critical role in mediating the influences of these stress hormones. The stress-induced activation of the amygdala and its interactions with other brain regions involved in processing memory play a critical role in ensuring that emotionally significant experiences are well-remembered. In this article, the effect of the amygdala and emotional arousal during memory lasting retention is reviewed.
