Individuals with high neuroticism had the decreased control functions of anterior cingulate cortex (ACC) over amygdala (emotion regions) and low socioeconomic status (SES) had negative effects on the functions of ACC. Based on these, we hypothesized that the decreased functions of ACC might make individuals with low SES had high level of neuroticism. According to the score of objective SES (OSES) and subjective SES (SSES) scales, subjects were divided into four groups (low SSES, high SSES, low OSES and high OSES) to investigate the roles of dynamic characteristics related to the ACC in the relationships between SES and neuroticism using resting-state EEG (RS-EEG) microstates analysis. It had been found that RS-EEG microstates can be divided into four types (MS1, MS2, MS3 and MS4) and the MS3 was related cingulo-opercular brain networks (including ACC and anterior insular). As our prediction, SSES had direct effects on neuroticism relative to OSES. Moreover, the neuroticism for low SSES was positively related to the occurrence and contribution of MS3, as well as the possibilities of transitions between MS3 and MS1. Based on these, we thought that low-SSES individuals might be more difficult to inhibit the negative emotions, especially inhibit the spontaneous thoughts related to these emotions.
具有高神经质的个体在前扣带皮层（ACC）对杏仁核（情绪区域）的控制功能降低，而低社会经济地位（SES）对 ACC 的功能有负面影响。基于这些，我们假设 ACC 的功能降低可能使 SES 较低的个体具有较高水平的神经质。根据客观 SES（OSES）和主观 SES（SSES）量表的得分，将受试者分为四组（低 SSES、高 SSES、低 OSES 和高 OSES），使用静息态 EEG（RS-EEG）微状态分析研究与 ACC 相关的动态特征在 SES 和神经质之间关系中的作用。已经发现，RS-EEG 微状态可以分为四种类型（MS1、MS2、MS3 和 MS4），MS3 与扣带回-脑岛网络（包括 ACC 和前岛叶）有关。正如我们所预测的，SSES 对神经质的直接影响大于 OSES。此外，低 SSES 的神经质与 MS3 的发生和贡献呈正相关，以及 MS3 与 MS1 之间的转换可能性。基于这些，我们认为低 SES 的个体可能更难抑制负面情绪，尤其是抑制与这些情绪相关的自发想法。
