Three Languages Share a Cortical Semantic Geometry
Recordings from 227 participants revealed cross-language relationships that strengthened toward higher-order association cortex.
Summary
Recordings from 227 participants revealed cross-language relationships that strengthened toward higher-order association cortex.
Chinese, English and French differ in form while carrying overlapping meaning. A multilingual decoding analysis of 227 participants found consistent relationships among cortical semantic representations across languages and people. The cross-language agreement increased from sensorimotor regions toward higher-order association cortex and aligned with the principal cortical functional gradient. The work identifies a population-level geometry in recorded data; it does not decode private thoughts or erase individual variation.
