本研究从神经激活的角度探讨了情绪何时调节工作记忆。使用功能磁共振成像，我们测量了大脑活动的编码和检索阶段的阅读广度测试（ESTA），使用情绪背景。情绪测试要求参与者在记忆句子中的目标单词时，阅读引起消极、神经或积极情绪状态的句子。在阅读阶段，与中性杏仁核相比，负性杏仁核激活右侧杏仁核。在海马旁回也发现了显著的激活，尽管只有在杏仁核的激活变得与中性杏仁核的激活相当之后。相反，相对于中性脑干，在阅读阶段，正脑干激活了黑质。这些发现表明，消极和积极的情绪通过不同的神经回路调节工作记忆。我们还讨论了情绪调节和工作记忆容量之间的可能关系。
The present study investigated when emotion modulates working memory from the perspective of neural activation. Using fMRI, we measured brain activity during the encoding and retrieval phases of a reading span test (RST) that used emotional contexts. The emotional RST required participants to read sentences that elicited negative, neural or positive emotional states while they were memorizing target words from the sentences. Compared with the neutral RST, the negative RST activated the right amygdala during the reading phase. Significant activation was also found in the parahippocampal gyrus, albeit only after activation of the amygdala became comparable to that in the neutral RST. In contrast, the positive RST activated the substantia nigra during the reading phase relative to the neutral RST. These findings suggest that negative and positive emotions modulate working memory through distinctive neural circuits. We also discuss possible relationships between emotional modulation and working memory capacity.
