- MIT researchers discovered 17 new brain regions beyond left hemisphere areas involved in language processing.
- These regions are scattered across cerebellum, hippocampus, and cerebral cortex, making up about 5% of brain volume.
- The study used fMRI data from over 700 people and a language localizer task to identify language-selective areas.
- Some newly identified regions, particularly in the cerebellum, also responded to nonlinguistic cognitive tasks.
- The findings challenge previous assumptions and open new avenues for studying language processing across the brain.
