Brain language processing mirrors AI layering, study finds
A Nature Communications study using intracranial EEG from nine epilepsy patients listening to a podcast found that the brain’s progression from raw sound to meaning aligns with the layer-by-layer processing of large language models, suggesting a shared hierarchical approach to language; however, this is an alignment of representations, not proof that brains run the same computations as AI, and further work is needed to see if these findings hold across more people, languages, and inputs.
