[Abstract] Objective The present study based on the systematic review of the MRI literature, on life satisfaction aimed to reveal the neural mechanism of life satisfaction.Materials and Methods We followed the systematic review process of preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines to acquire overall existing MRI studies on life satisfaction, extracted the research data, including the imaging modality, the measure of life satisfaction and the relevant indicators of brain structure and function, and further conducted a complied analysis to the results in different brain regions.Results Fifteen studies were totally involved. We found a widespread correlation pattern between life satisfaction and brain. These associations primarily concentrated in the prefrontal cortex, and the structures and functions in the regions of limbic system, temporal lobe, parietal lobe and occipital lobe were also related to life satisfaction.Conclusions The structure and function of prefrontal cortex were of great significance to life satisfaction, and it may coordinate with other related brain regions of the limbic system, temporal lobe, parietal lobe and occipital lobe to influence the individuals' social behavior and the subjective experience through participating in the cognition, emotion and memory functions, so as to be strongly associated with life satisfaction.
