摘要:  白鼠和人类都对情绪唤醒的经历有更好的记忆。情绪唤醒影响记忆巩固的神经生理机制主要有以下几种方式:(a)情绪唤醒或急性应激, 会引发个体内部应激激素的释放, 从而增强其记忆巩固过程。(b1)杏仁核的激活对情绪唤醒影响记忆巩固过程十分重要, 杏仁核内部去甲肾上腺素(NE)的释放影响记忆巩固过程。(b2)杏仁核投射到负责不同类型记忆加工的脑区, 如海马和皮层, 从而影响记忆。(c)应激激素影响记忆巩固的过程中, 杏仁核内NE的激活在这一过程中扮演着重要角色。综上, 情绪唤醒影响记忆巩固的过程, 涉及到激素调节、神经调节及二者的共同作用。

Abstract:  The studies indicate both rats and humans had better memory recall under emotionally arousing experiences situation. This paper presents the neurobiological mechanisms for the influence of emotional arousal on memory consolidation, including: (a) Emotional arousal or stress released the adrenal stress hormones leading to enhance the consolidation of lasting memories. (b1) The activation of amygdala mediated the consolidation of emotional arousal. The release of Norepinephrine (NE) within amygdala affected the consolidation of memory. (b2) Amygdala regulation of memory projected to brain systems, such as hippocampus or cortex, which engaged in different kinds of memory experiences. (c) The activation of NE in the amygdala played an important role in the process of stress-induced memory consolidation. In summary, the effect of emotional arousal on memory consolidation involved hormonal regulation, neural modulation and their interaction.

Key words:  emotional arousal, stress hormones, amygdala, memory consolidation
