A population code for semantics in human hippocampus

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.

Electrophysiological features of signals recorded from white matter

The paper analyzes electrophysiological signals from white matter and finds they have distinct spectral features and higher complexity compared to gray matter.

Shared neural geometries for bilingual semantic representations in human hippocampal neurons

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

A semantotopic map in human hippocampus

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

Linguistic contextualization in the human hippocampus

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

EGR3 Deletion Rescues Developmental and Epileptic Encephalopathy in Kcna1-null Mice

This study shows that deleting EGR3 in Kcna1-null mice rescues seizures, behavior, and brain pathology, linking early seizures to long-term transcriptional changes.

Plasticity and Language in the Anesthetized Human Hippocampus

This study shows that the human hippocampus can process oddball tones and language stimuli, including semantic and grammatical features, even under general anesthesia.

Plural molecular and cellular mechanisms of pore domain KCNQ2 encephalopathy

The paper investigates the molecular and cellular mechanisms of KCNQ2 encephalopathy through structural analysis, functional assays, and an animal model, revealing multiple pathogenic effects of the G256W variant.

Clinicopathologic Dissociation: Robust Lafora Body Accumulation in Malin KO Mice Without Observable Changes in Home-cage Behavior

This study shows that malin-deficient mice accumulate Lafora bodies without observable neurobehavioral decline, suggesting a delay between LB accumulation and clinical symptoms.

Actigraphic Correlates of Neuropsychiatric Disability in Adult Patients with Focal Epilepsy

This study examines how activity patterns in patients with focal epilepsy correlate with neuropsychiatric symptoms, finding associations between RAR features and depression, anxiety, and sleepiness.

On the Mental Status of Stargazer Mice

This study examines the neurobehavioral phenotype of Stargazer mutant mice, revealing a syndrome with ataxia, hyperactivity, and behavioral abnormalities linked to Cacng2 disruptions.

Intracranial EEG spectral feature analysis and focal brain stimulation reveal affective specialization within dorsal anterior cingulate cortex

The paper uses intracranial EEG to analyze spectral features in the dorsal anterior cingulate cortex, revealing hemispheric specialization for valence and intensity processing and showing causal effects of stimulation on emotional face perception.

On the Digital Psychopharmacology of Valproic Acid in Mice

This study examines the effects of valproic acid on mouse behavior and development using home-cage monitoring and pup open field assays, identifying behavioral changes linked to psychiatric and developmental outcomes.

Home-cage Monitoring Ascertains Signatures of Ictal and Interictal Behavior In Mouse Models of Generalized Seizures

This study uses home-cage monitoring to identify ictal and interictal behavioral changes in mouse seizure models, revealing distinct behavioral and convulsive severity profiles.
