Claim Verification: "The human brain does not generate new neurons in adulthood." — Disproved

Automated fact-verification of the claim: "The human brain does not generate new neurons in adulthood." Verdict: DISPROVED Key Findings 3 of 3 independent peer-reviewed sources directly confirm that the human brain generates new neurons in adulthood — meeting the threshold of ≥ 3 required to disprove the claim. Moreno-Jiménez et al. 2019 (Nature Medicine) identified thousands of immature neurons in the dentate gyrus of neurologically healthy humans up to the 9th decade of life (B1, verified). Kempermann et al. 2018 (Cell Stem Cell, 18 co-authors) concluded there is "no reason to abandon the idea that adult-generated neurons make important functional contributions to neural plasticity and cognition across the human life span" (B2, verified). Llorens-Martín et al. 2021 (Journal of Neuroscience) concluded that "adult neurogenesis is a robust phenomenon that occurs in the human hippocampus" and persists until the 10th decade of life (B3, verified). All three citations were verified by live fetch against the source pages (tier 5 / government domain, nih.gov).

Moreno-Jiménez等人2019年发表于《Nature Medicine》的研究，在神经系统健康人群的齿状回中发现了数千个未成熟神经元，样本年龄跨度可达90岁（B1，已核实）。 2. Kempermann等人2018年发表于《Cell Stem Cell》的研究（共18位合作作者）得出结论："没有理由放弃‘成年新生神经元对人类全生命周期的神经可塑性与认知具有重要功能性贡献’这一观点"（B2，已核实）。 3. Llorens-Martín等人2021年发表于《Journal of Neuroscience》的研究得出结论："成年神经发生（adult neurogenesis）是发生在人类海马体中的稳定现象，并可持续至100岁年龄段"（B3，已核实）。 上述三篇参考文献均通过实时抓取来源页面完成核实（层级5/政府域名：nih.gov）。 相关文件 proof.py — 可重复运行的Python核查脚本 proof.md — 结构化核查报告 proof_audit.md — 完整核查审计追踪记录 proof_narrative.md — 通俗语言总结报告 proof.json — 机器可读结构化数据 本报告由Proof Engine v0.10.0生成。
