BACKGROUND: Brain science research is considered the crown jewel of 21st-century scientific research; the United States, the United Kingdom, and Japan have elevated brain science research to a national strategic level. This study employs bibliometric analysis and knowledge graph visualization to map global trends, research hotspots, and collaborative networks in brain science, providing insights into the field's evolving landscape and future directions. METHODS: We analyzed 13,590 articles (1990-2023) from the Web of Science Core Collection using CiteSpace and VOSviewer. Metrics included publication volume, co-authorship networks, citation patterns, keyword co-occurrence, and burst detection. Analytical tools such as VOSviewer, CiteSpace, and online bibliometric platforms were employed to facilitate this investigation. RESULTS: The United States, China, and Germany dominated research output, with China's publications rising from sixth to second globally post-2016, driven by national initiatives like the China Brain Project. However, China exhibited limited international collaboration compared to the United States and European Union. Key journals included Human Brain Mapping and Journal of Neural Engineering, while emergent themes centered on "task analysis," "deep learning," and "brain-computer interfaces" (BCIs). Research clusters revealed three focal areas: (1) Brain Exploration (e.g., fMRI, diffusion tensor imaging), (2) Brain Protection (e.g., stroke rehabilitation, amyotrophic lateral sclerosis therapies), and (3) Brain Creation (e.g., neuromorphic computing, BCIs integrated with AR/VR). Despite China's high output, its influence lagged in highly cited scholars, reflecting a "quantity-over-quality" challenge. CONCLUSION: Brain science research is in a golden period of development. This bibliometric analysis offers the first comprehensive review, encapsulating research trends and progress in brain science. It reveals current research frontiers and crucial directions, offering a strategic roadmap for researchers and policymakers to navigate countries when planning research layouts.
背景：脑科学研究被视为21世纪科学研究的皇冠明珠；美国、英国和日本已将脑科学研究提升到国家战略层面。本研究采用文献计量分析和知识图谱可视化技术，绘制脑科学领域的全球趋势、研究热点和合作网络，深入了解该领域不断演变的格局和未来发展方向。 方法：我们使用CiteSpace和VOSviewer分析了来自科学网核心合集（1990 - 2023年）的13590篇文章。指标包括发表量、合著网络、引用模式、关键词共现和突发检测。采用VOSviewer、CiteSpace和在线文献计量平台等分析工具来推动这项研究。 结果：美国、中国和德国在研究产出方面占据主导地位，中国的出版物在2016年后从全球第六位升至第二位，这得益于“中国脑计划”等国家举措。然而，与美国和欧盟相比，中国的国际合作有限。主要期刊包括《人类脑图谱》和《神经工程学杂志》，新兴主题集中在“任务分析”、“深度学习”和“脑机接口”（BCIs）。研究集群揭示了三个重点领域：（1）脑探索（如功能磁共振成像、扩散张量成像），（2）脑保护（如中风康复、肌萎缩侧索硬化症治疗），以及（3）脑创造（如神经形态计算、与增强现实/虚拟现实集成的脑机接口）。尽管中国的产出很高，但其在高被引学者方面的影响力滞后，反映出“重数量轻质量”的挑战。 结论：脑科学研究正处于黄金发展期。这项文献计量分析提供了首次全面综述，概括了脑科学的研究趋势和进展。它揭示了当前的研究前沿和关键方向，为研究人员和政策制定者在规划研究布局时提供了一份战略路线图，以指导各国开展研究。
