The paper investigates how semantic information is encoded in human hippocampal activity during speech processing, finding that distributed neural patterns capture semantic relationships similar to language models.

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.

The paper identifies simplex-shaped neural manifolds for number representation in the human medial temporal lobe and finds similarities with large language models.

The paper investigates how bilinguals represent semantic concepts in two languages, finding shared neural geometries that support translation despite language-specific neuron responses.

This study uses large language models to analyze neural responses in autistic individuals, finding reduced contextualization signatures compared to controls.

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.

The paper investigates how neural circuits in the human hippocampus and anterior cingulate cortex support multiple tasks, finding shared neural subspaces across distinct behaviors.

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

The paper maps semantic organization in the human hippocampus, finding semantotopic patterns and multiscale semantic similarity along the mediolateral axis.

The paper shows hippocampal neurons encode meanings of spoken and heard words using shared geometric embeddings, enabling abstract cross-personal representations while preserving speaker identity binding.

The paper shows that hippocampal neurons encode word position and context in a way similar to self-attention in large language models.

The paper examines brain activity during a continuous prey-pursuit task, identifying distinct roles for hippocampus, ACC, and OFC in decision-making processes.

The paper investigates how hippocampal neurons track multiple agents during pursuit tasks, finding multiplexed neural maps and semi-orthogonal subspaces for distinguishing agents.
