Abstract： The relationship of Socioeconomic status (SES) and human brain structure/function, has great significance of understanding the effects of socioeconomic factors on the psychology and behavior and preventing the brain/mental illness. Over the past decade, researchers have used cognitive neuroscience to explore the relationship between SES and the brain, finding that SES indicators are related to brain structure and function, but it remains unclear whether the conclusions of different studies are consistent. This paper reviews the researches on SES and brain, from the perspective of brain structure and function, and from the perspectives of cognition and emotion. It was found that (1) structurally, SES level may be related to the hippocampus and frontal lobe, which are considered responsible for memory and executive function, as well as the limbic system involved in emotional processing.(2) functionally, the brain regions related to executive function, learning and memory may differ in activity patterns in individuals with different SES levels. and SES is also related to the brain activity induced by emotions and rewards. It is worth noting that due to challenges such as the complexity of SES, the dynamic nature of brain development, the multi-layered influence of SES on the brain and methodological rigor, stable conclusions cannot be drawn from the current research. Therefore, this paper further points out that future research should not only tackle the above challenges, but also consider the impact of cultural differences, so as to turther understand the relationship between SES and brain and provide guidance for social policies."
