Rare dysfunctional SCN2A variants are associated with malformation of cortical development
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
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
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.

Frequency‐specific alterations in brain connectivity induced by pulvinar stimulation
Abstract Objective Deep brain stimulation (DBS) is emerging as a promising therapy for patients with drug‐resistant epilepsy, particularly those who are either unsuitable for or unresponsive to resective surgery. The potential benefit of DBS in these patients may stem from its ability to reduce excessive brain functional connectivity (FC).

Abstract Objective Mild malformations of cortical development with oligodendroglial hyperplasia in epilepsy (MOGHE) are brain lesions associated with focal epilepsy and characterized by increased oligodendroglial density, heterotopic neurons, and hypomyelination in the white matter.

Type I interferon signalling and interferon‐responsive microglia in health and disease
Recent insights reveal that type I interferon (IFN‐I) signalling plays critical roles in the nervous system beyond antiviral defence. Dysregulated IFN‐I activity is increasingly linked to neurological dysfunction and neurodegeneration, with microglia as central mediators. This review explores the broader impact of IFN‐I signalling on the nervous system

Estrogenic regulation of hippocampal inhibitory system across lifespan
Abstract Estrogens produced in peripheral tissues and locally in the brain are potent neuromodulators. The function of the hippocampus, a brain region essential for episodic memory and spatial navigation, relies on the activity of ensembles of excitatory neurons whose activity is temporally and spatially coordinated by a wide diversity of inhibitory ...

Abstract Kisspeptin (KP) signaling in the brain is defined by the anatomical distribution of KP‐producing neurons, their fibers, receptors, and connectivity. Technological advances have prompted a re‐evaluation of these chemoanatomical aspects, originally studied in the early years after the discovery of KP and its receptor Kiss1r.
