Rare dysfunctional SCN2A variants are associated with malformation of cortical development

open access: yesEpilepsia, Volume 66, Issue 3, Page 914-928, March 2025.
Abstract Objective SCN2A encodes the voltage‐gated sodium (Na+) channel α subunit NaV1.2, which is important for the generation and forward and back propagation of action potentials in neurons. Genetic variants in SCN2A are associated with a spectrum of neurodevelopmental disorders.

Preferential superficial cortical layer activation during seizure propagation

open access: yesEpilepsia, Volume 66, Issue 3, Page 929-941, March 2025.
Abstract Objective Focal cortical seizures travel long distances from the onset zone, but the long‐distance propagation pathways are uncertain. In vitro and in vivo imaging techniques have investigated the local spread of seizures but did not elucidate long‐distance spread. Furthermore, classical studies in slices suggested seizure spread locally along

Fast activity chirp patterns in focal seizures from patients and animal models

open access: yesEpilepsia, Volume 66, Issue 3, Page 621-631, March 2025.
Abstract Time–frequency analysis of focal seizure electroencephalographic signals performed with depth electrodes in human temporal lobe structures has revealed the occurrence at onset of oscillations at approximately 30–100 Hz that feature a monotonic rapid decay in frequency content.

Neuronal oscillatory imbalances in GNAO1‐related disorders associated with disease severity

open access: yesEpilepsia, EarlyView.
Abstract Objective This study investigates excitatory/inhibitory (E/I) imbalances in GNAO1‐related disorders (GNAO1‐RD), linking neuronal dysfunction to clinical severity using E/I‐sensitive electroencephalography (EEG) analyses. Methods We conducted an observational study involving 12 children with GNAO1‐RD caused by pathogenic variants and 36 age ...
