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.

Convergent Inhibitory Cortical Circuit Disruption Drives Genetically Distinct Absence Seizures

This study identifies a common inhibitory cortical circuit disruption in two genetically distinct absence epilepsy mouse models that leads to seizure onset.

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.

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.

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.

Removal of KCNQ2 from Parvalbumin-expressing Interneurons Improves Anti-Seizure Efficacy of Retigabine

This study shows that removing KCNQ2 from parvalbumin-expressing interneurons enhances the anti-seizure efficacy of retigabine.

Right lateralized posterior parietal theta-gamma coupling during sustained attention in mice

The paper examines theta-gamma coupling in the posterior parietal cortex of mice during sustained attention tasks and finds greater right hemisphere activity correlates with task accuracy.

Asynchronous suppression of visual cortex during absence seizures

The paper examines neuronal activity in the visual cortex of stargazer mice during absence seizures, finding asynchronous suppression of most neurons.
