2025). Tools like VOSviewer enable visualization of co‐authorship networks, keyword co‐occurrence, and citation patterns (Canul‐Medina et al. 2024). For example, Jin et al. (2025) used VOSviewer to map biomarker research in schizophrenia, revealing clusters around “genetics,” “proteomics,” and genes like NRXN1 and CNTNAP2. Another study explored the global landscape of schizophrenia and serotonin research, highlighting genetic concepts such as “pharmacogenetics” and “epigenetics” (Canul‐Medina et al. 2024). This evidence concerns the gene NRXN1 and schizophrenia.
