ABSTRACT
@#Objective To investigate the development, hot spots and trends of event-related potentials for cognitive function research. Methods The literatures about application of event-related potentials in cognitive function research from 2011 to 2021 in CNKI and Web of Science core collection database were retrieved. The countries, authors, institutions, cited reference and keywords were extracted with CiteSpace to draw knowledge mapping. Results The most of researches came from the United States. For China, the author published the most researches was Zhan Xianghong, and the institute was the West China Mental Health Center of Sichuan University; the keywords such as P300 and depression were the most frequent, and researches focused on Alzheimer's disease, depression and schizophrenia, etc., which tended to use negative correlation changes of event-related potentials. Internationally, the author publishing the most researches was christian beste, and the institute was University of California, San Diego. The keywords such as attention and electroencephalograph were the most frequent, and researches focused on Alzheimer's disease and bipolar disorder, etc., which tended to focus on the P300 theta oscillation. Conclusion The application of event-related potential in cognitive function remains heat, to explore the cognitive dysfunction after various diseases.
