The Benefits of Video Games on Brain Cognitive Function: A Systematic Review of Functional Magnetic Resonance Imaging Studies

Benefits of video games on cognitive function have been proved by increasing evidence. However, reasons for game-induced changes in cognitive function are still elusive. Therefore, this study conducted a systematic review of brain function activation changes in association with video games. We retrieved publications from three electronic databases (PubMed, Web of Science, and PsycInfo), with publication dates before 8 February 2021. After screening the study with fMRI data, 13 studies were included in this work, including 9 cross-sectional studies and 4 types of research. In this review, we summarized the potential benefits of video games on cognitive function and discussed the effects of different types of video games on cognitive function. In particular, we highlighted the effect of video games on attention ability and visuospatial ability and addressed the functional brain activation changes in frontal and parietal lobes and other related brain regions induced by games. Finally, we pointed out that when discussing the effect of video games on brain function, types of video games should be carefully categorized.
