biostudies-literatureUnknown14Liu G<h4>Background</h4>Microglia have been identified for a century. In this period, their ontogeny and functions have come to light thanks to the tireless efforts of scientists. However, numerous documents are being produced, making it challenging for scholars, especially those new to the field, to understand them thoroughly. Therefore, having a reliable method for quickly grasping a field is crucial.<h4>Methods</h4>We searched and downloaded articles from the Web of Science Core Collection with "microglia" or "microglial" in the title from 2002 to 2021. Eventually, 12,813 articles were located and, using CiteSpace and VOSviewer, the fundamental data, knowledge domains, hot spots, and emerging trends, as well as the influential literature in the field of microglia research, were analyzed.<h4>Frontiers in aging neuroscience1057214https://www.ebi.ac.uk/biostudies/studies/S-EPMC9849393biostudies-literatureKnowledge domains and emerging trends of microglia research from 2002 to 2021: A bibliometric analysis and visualization study.PMC9849393Li TZhang XFeng WYang AQi SLiu GfalseKnowledge domains and emerging trends of microglia research from 2002 to 2021: A bibliometric analysis and visualization study.<h4>Background</h4>Microglia have been identified for a century.
