摘要
目的 了解功能磁共振成像(Function Magnetic Resonance Imaging,fMRI)在认知功能领域的研究进展、热点趋势以及未来发展方向.方法 检索2012-2022年CNKI和Web of Science数据库中关于fMRI在认知功能研究中应用的中英文文献.借助CiteSpace和VOSviewer软件对发文的国家、作者合作关系、发文机构、被引频次和关键词进行可视化分析.结果 CNKI文献纳入研究1220篇,发文量逐年增长,合作团体较少,机构内部合作紧密,发文量最高的机构是首都医科大学宣武医院;关键词"低频振幅""功能连接"出现的频次较高,研究集中于糖尿病、抑郁症、痴呆等疾病,主要关注注意力、记忆、短时记忆、执行功能等认知功能.Web of Science文献纳入研究10056篇,文献中作者形成多个合作团体,团体之间合作紧密,发文量最高的机构是Harvard Medical School,关键词"functional connectivity""brain network""default mode network"等出现频次较高,研究集中于阿尔茨海默病、轻度认知障碍等疾病,主要关注注意力、工作记忆、情景记忆以及执行功能.结论 中文和英文文献中对于fMRI在认知功能中的研究热度保持稳定,已对多种疾病展开认知功能研究.
Abstract
Objective To understand the research progress,hot trend and future development direction of functional magnetic resonance imaging(fMRI)in the field of cognitive function.Methods The Chinese and English literatures on the application of fMRI in cognitive function research in CNKI and Web of Science database from 2012 to 2022 were searched.With the help of CiteSpace and VOSviewer software,country,author's cooperation relationship and affiliation,the cited frequency and keywords were visually analyzed.Results In the CNKI database,there were 1220 literatures included in the study.The study found that the number of publications increased year by year,with few cooperative groups and close cooperation within institutions.Xuanwu Hospital of Capital Medical University had the highest number of publications.The frequency of keywords"low-frequency amplitude"and"functional connection"was high,and the research focused on diseases such as diabetes,depression,dementia,and concerned about cognitive functions such as attention,memory,short-term memory and executive function.In the Web of Science database,10056 literatures were included in the study,in which authors formed a number of cooperative groups,and the groups cooperated closely with each other.Harvard Medical School had published the highest number of papers.Key words such as"functional connection","brain network"and"default mode network"had a high frequency.These literatures focused on diseases such as Alzheimer's disease and mild cognitive impairment,and concerned about attention,working memory,episodic memory and executive function.Conclusion The research interest of fMRI in cognitive function remains stable in both Chinese and English literatures,and cognitive function research has been carried out in a variety of diseases.
