流畅而有效的社会沟通需要在视觉短期记忆（VSTM）中编码和维护面部身份和情感表达信息，以实现对世界及其参与者的连贯，持续的描述。当面对潜在的威胁性情绪表现时，这似乎具有特别的进化重要性-以前的研究表明，愤怒与快乐或中性面孔身份的VSTM更好。使用功能性磁共振成像，在这里，我们调查了VSTM中这种愤怒表情的神经相关性。参与者被展示了一到四个要记住的愤怒，快乐或中性的面孔，并在短暂的保留延迟后，他们说是否有一个单一的探针脸已经出现在以前的显示。任何一个显示器中的所有面孔都表达了相同的情绪，这项任务需要对面孔身份的记忆。我们发现增强的VSTM愤怒的脸的身份和描述的右半球的大脑网络支持这种效果，其中涉及苍白球，上级颞沟，额叶。苍白球活动的增加与VSTM中的愤怒益处显著相关。受情绪调节的区域与受记忆负荷调节的区域不同。我们的研究结果为基底神经节作为情绪和认知之间的界面的关键作用提供了证据，并得到了额叶，颞叶和枕叶网络的支持。
Fluid and effective social communication requires that both face identity and emotional expression information are encoded and maintained in visual short-term memory (VSTM) to enable a coherent, ongoing picture of the world and its players. This appears to be of particular evolutionary importance when confronted with potentially threatening displays of emotion - previous research has shown better VSTM for angry versus happy or neutral face identities. Using functional magnetic resonance imaging, here we investigated the neural correlates of this angry face benefit in VSTM. Participants were shown between one and four to-be-remembered angry, happy, or neutral faces, and after a short retention delay they stated whether a single probe face had been present or not in the previous display. All faces in any one display expressed the same emotion, and the task required memory for face identity. We find enhanced VSTM for angry face identities and describe the right hemisphere brain network underpinning this effect, which involves the globus pallidus, superior temporal sulcus, and frontal lobe. Increased activity in the globus pallidus was significantly correlated with the angry benefit in VSTM. Areas modulated by emotion were distinct from those modulated by memory load. Our results provide evidence for a key role of the basal ganglia as an interface between emotion and cognition, supported by a frontal, temporal, and occipital network.
