Figure 1. — Main mechanisms involved in the memory-enhancing effect of emotion. Emotion enhances long-term episodic memory by modulating activity in two main memory-related brain regions, the medial–temporal lobe (MTL) memory system and the prefrontal cortex (PFC). However, the effects of emotion on MTL and PFC regions may be related to different mechanisms: AMY and MTL are part of basic/direct neurohormonal mechanisms underlying the memory-enhancement effect of emotion (bottom-up mechanism), whereas PFC is part of a mechanism (also including the parietal cortex—PC) that has an indirect/mediated involvement in the formation of emotional memories, by enhancing strategic, semantic, working memory, and attentional processes (top–down mechanism).
