Negative stimuli are often remembered better than neutral stimuli, which is called the emotional enhancement of memory (EEM). We tested whether the role of the ventrolateral prefrontal cortex (VLPFC) in the EEM depended on stimulus valence and/or arousal, and attentional resources. Continuous theta burst stimulation (cTBS) was applied over the left VLPFC, right VLPFC and vertex before encoding 'negative arousing,' 'negative nonarousing,' and 'neutral' words under full and divided attention, followed by a recognition test. The vertex condition showed the EEM effect for 'negative arousing' and 'negative nonarousing' words. However, the right VLPFC condition showed no evidence of the EEM effect for 'negative arousing' or 'negative nonarousing' words, under full attention. In contrast, the left VLPFC condition showed the EEM effect for 'negative arousing' words, but not 'negative nonarousing' words, under full attention. Thus, the left and right VLPFC have different roles in the EEM, depending on valence and arousal.
负面刺激通常比中性刺激记忆得更好，这被称为记忆的情绪增强效应（EEM）。我们测试了腹外侧前额叶皮层（VLPFC）在EEM中的作用是否取决于刺激效价和/或唤醒程度以及注意力资源。在全神贯注和注意力分散的情况下，对左侧VLPFC、右侧VLPFC和头顶进行连续theta爆发刺激（cTBS），然后对“负面唤醒”、“负面非唤醒”和“中性”词汇进行编码，随后进行识别测试。头顶条件显示了对“负面唤醒”和“负面非唤醒”词汇的EEM效应。然而，在全神贯注的情况下，右侧VLPFC条件未显示出对“负面唤醒”或“负面非唤醒”词汇的EEM效应证据。相比之下，在全神贯注的情况下，左侧VLPFC条件显示了对“负面唤醒”词汇的EEM效应，但对“负面非唤醒”词汇没有该效应。因此，根据效价和唤醒程度，左侧和右侧VLPFC在EEM中具有不同的作用。
