功能成像研究检查了哪些大脑区域对情绪刺激做出反应，但尚未确定稳定的人格特征如何调节这种大脑激活。外向性和神经质这两种人格特征与情绪体验密切相关，因此可能会调节大脑对情绪刺激的反应。本研究使用功能磁共振成像直接测试健康女性大脑对情绪刺激反应的个体差异是否与外向性和神经质相关。外向性与局部大脑区域对积极刺激的大脑反应相关，神经质与局部大脑区域对消极刺激的大脑反应相关。这项研究提供了直接证据，证明人格与大脑对情绪刺激的反应有关，并确定了发生这种调节的常见和独特的大脑区域。
Functional imaging studies have examined which brain regions respond to emotional stimuli, but they have not determined how stable personality traits moderate such brain activation. Two personality traits, extraversion and neuroticism, are strongly associated with emotional experience and may thus moderate brain reactivity to emotional stimuli. The present study used functional magnetic resonance imaging to directly test whether individual differences in brain reactivity to emotional stimuli are correlated with extraversion and neuroticism in healthy women. Extraversion was correlated with brain reactivity to positive stimuli in localized brain regions, and neuroticism was correlated with brain reactivity to negative stimuli in localized brain regions. This study provides direct evidence that personality is associated with brain reactivity to emotional stimuli and identifies both common and distinct brain regions where such modulation takes place.
