Estimation of neuronal tuning for word meaning from passively recorded naturalistic speech

The paper develops a pipeline to estimate neuronal tuning for word meaning from naturalistic speech and validates it using patient data and ground-truth controls.

Polysemanticity in human hippocampal neurons

This study shows that human hippocampal neurons use polysemantic coding, where neurons represent multiple unrelated semantic features through high-dimensional superposition, enabling efficient contextualization of meaning.

A geometric foundation for word meaning in the brain

The paper shows that semantic features in word meaning are encoded in the brain through geometric structures similar to those in language models.
