情景情绪记忆模型通常关注为什么情绪事件比中性事件更容易被记住，重点关注杏仁核和其他内侧颞叶区域之间的相互作用。但情感事件的记忆可以通过情感基调和框架来区分。我们认为，背内侧前额叶皮层（dmPFC）是一个越来越被认为具有横切社会情感和认知领域的区域，在情绪记忆的这方面发挥着关键作用。在简要回顾了 dmPFC 在控制从行动、情绪到社会认知等行为中的作用后，我们深入研究了越来越多的证据，表明它的功能还有助于从事件中抽象意义和控制记忆，特别是情绪记忆。它的作用始于情感体验的编码，持续到情感体验的稳定，并在记忆内容的检索过程中持续存在。在每个阶段，dmPFC 参与记忆的情感和认知成分的整合，建立强调或弱化情感内容的网络和框架。将 dmPFC 纳入情景情绪记忆模型应该有助于理解记忆中经历的情感基调。
Models of episodic emotional memory typically concern why emotional events are more likely to be remembered than neutral events, focusing on interactions between the amygdala and other medial temporal lobe regions. But memories of emotional events can be distinguished by their affective tone and framing. We propose that the dorsomedial prefrontal cortex (dmPFC), a region that is increasingly recognized to crosscut socio-affective and cognitive domains, plays a key role in this aspect of emotional memory. After briefly reviewing the role of the dmPFC in the control of behaviors ranging from actions to emotions to social cognition, we delve into the accumulating evidence that its functions also subserve the abstraction of meaning from events and the control of memories, particularly emotional memories. Its role begins during the encoding of emotional experiences, continues through their stabilization, and endures during the retrieval of memory content. At each phase, the dmPFC participates in the integration of affective and cognitive components of memories, setting up networks and framings that either emphasize or de-emphasize emotional content. Incorporating the dmPFC into models of episodic emotional memory should provide leverage in understanding the affective tone with which experiences are brought to memory.
