MIT脑与认知科学副教授Evelina Fedorenko领导的研究团队发现，大脑可以在不依赖语言系统的情况下进行逻辑推理1。这项发表于《美国国家科学院院报》2026年123卷第28期的研究表明，即使语言处理能力严重受损的中风患者也能像正常人一样解决复杂逻辑谜题1。
研究人员对两名有严重语言障碍的中风患者进行了测试，包括数字规则识别任务和几何图案矩阵推理任务1。脑成像扫描结果显示，语言系统在归纳推理和演绎推理中都未被激活1。这一发现证明了语言和逻辑推理由大脑的不同系统驱动1。
Fedorenko表示，研究结果"增加了大量证据，表明即使严重失语症患者也能保留其抽象逻辑思维能力"1。扫描数据还显示，多需求网络在归纳推理中保持活跃，但在演绎推理中未参与1。
Researchers at MIT have found that logical reasoning operates independently from language processing in the brain.1 A study led by Evelina Fedorenko, an associate professor of brain and cognitive sciences at MIT, demonstrates that even stroke patients with severe language impairments can solve complex logic puzzles as effectively as individuals without such deficits.1 Brain imaging scans revealed that language-processing regions remain inactive during reasoning tasks, indicating that language and logical reasoning are driven by distinct neural systems.1
The research, published in the Proceedings of the National Academy of Sciences in August 2026, involved two stroke patients with significant language disorders alongside a control group.1 Participants completed tests including digit-rule identification tasks and geometric pattern matrix reasoning tasks.1 Brain imaging showed that the language system was not activated during either inductive or deductive reasoning, while the multiple-demand network was active during inductive reasoning but not during deductive reasoning.1 According to Fedorenko, the findings "add substantial evidence that even patients with severe aphasia retain their ability for abstract logical thinking."1
