MRI scans of healthy adults confirmed it: the brain's language-processing regions stayed quiet during reasoning tasks, while a separate \"multiple demand\" network handled the logic, engaging for inductive reasoning but not deductive reasoning.\n\nPublished July 8 in the Proceedings of the National Academy of Sciences, the findings push back on the philosophical assumption that thought requires language and could reshape how researchers view aphasia — showing that language loss does not mean a loss of reasoning ability. The team says the work may also inform how AI models are built to reason."}}
