Bibliometric Study of fMRI Research in Disorders of Consciousness, 2009-2025

418 publications from 39 countries analyze the evolution of functional magnetic resonance imaging (fMRI) applications in prolonged disorders of consciousness (pDoC). The bibliometric data, compiled by Xi-Chen Wang, covers research from 2009 to September 2025 and identifies the United States, China, and Belgium as central contributors. Core scholars and key research hotspots, such as resting-state fMRI and Cognitive-Motor Dissociation, are mapped through co-citation and keyword analysis.

Use Cases

• Mapping publication trends and country-level contributions in fMRI for pDoC based on the bibliometric analysis.
• Identifying core academic networks and influential scholars like Steven Laureys based on co-citation data.
• Analyzing keyword evolution to track research hotspots such as resting-state fMRI and covert consciousness.
• Supplementing bibliometric findings with narrative synthesis of recent clinical trials mentioned in the description.

Strengths

• Contains 418 analyzed articles and reviews, providing a substantive corpus for analysis.
• Covers a 16-year time range from 2009 to September 2025, showing longitudinal trends.
• Includes data from 39 countries or regions, offering a multinational perspective.
• Explicitly identifies core scholars and the most cited journal (NeuroImage).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale analysis.
• The 13.0 KB file size suggests the dataset is very small, likely containing summary tables rather than raw bibliographic records.
