事件相关电位应用于认知功能研究的可视化分析北大核心CSCD

目的了解事件相关电位应用于认知功能研究的发展构架、研究热点和趋势。方法检索2011年至2021年中国知网和Web of Science核心合集数据库关于事件相关电位在认知功能研究中应用的文献。应用CiteSpace软件对文献的来源地、作者、机构、被引文献和关键词进行可视化,绘制知识图谱。结果发文量最多的国家是美国。国内发文量最高的作者是詹向红,发文量最高的机构是四川大学华西心理卫生中心;关键词以P300、抑郁症等频次较高,研究集中于阿尔茨海默病、抑郁症、精神分裂症等疾病,主要关注事件相关电位的关联性负变。国际发文量最高的作者是Christian Beste,发文量最高的机构是加州大学圣地亚哥分校,关键词以注意力、脑电等频次较高,研究集中于阿尔茨海默病、双向情感障碍等疾病,主要关注P300的θ振荡。结论国内外对事件相关电位在认知功能中的研究热度保持稳定,可对多种疾病展开认知功能研究。

Event-related potential for cognitive function research:a visual analysis

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.
