Visual analysis of functional near-infrared spectroscopy research
BACKGROUND:In recent years,functional near-infrared spectroscopy has shown extensive research significance and application potential in the fields of cognitive neuroscience,clinical medicine,and engineering technology due to its portability,low cost,non-invasiveness,and high temporal resolution.OBJECTIVE:To analyze the research progress,hot issues,and frontier trends of functional near-infrared spectroscopy in the past 10 years.METHODS:Web of Science database was searched for articles related to functional near-infrared spectroscopy published from January 1,2013 to November 30,2023.CiteSpace and VOSviewer software was used to conduct a visual analysis of publication statistics,journals,countries,institutions,authors,and keywords.RESULTS AND CONCLUSION:This article included a total of 2 714 documents,showing an overall upward trend in the volume of literature concerning functional near-infrared spectroscopy over the past decade.The 2 714 documents selected for this article were authored by 9 171 researchers from 2 400 institutions across 68 countries in 495 kinds of journals.The United States and University College London are representative countries and institutions,while Ehlis and Fallgatter are two influential authors in this research field.The journal NeuroImage ranks first with the highest citation rate.Functional near-infrared spectroscopy research primarily comes from University College London in the UK,Beijing Normal University in China,and the University of Tübingen in Germany.The keyword co-occurrence network map generated using VOSviewer 1.6.20 reveals six research clusters.By analyzing the specific keywords of each cluster,we further understand the research hotspots in this field.The burst analysis of keywords uncovers the research frontiers and development trends,providing important guidance for future research directions of functional near-infrared spectroscopy.
