Reflex seizures and epilepsy surgery: A network approach case‐based exploration

open access: yesEpileptic Disorders, EarlyView.
Abstract Context Reflex seizures (RS) are defined by their consistent provocation by specific stimuli, encompassing a broad range from elementary sensory inputs to complex cognitive tasks. While RS are often encountered in clinical practice, their surgical management remains sparsely reported and poorly systematized.

Hippocampal network activity changes during early epileptogenesis predict subsequent epilepsy

open access: yesEpilepsia, EarlyView.
Abstract Objective Despite decades of research, the circuit mechanisms that underlie focal epileptogenesis remain incompletely understood. In this study, we aimed to characterize the changes in hippocampal network activity induced by an epileptogenic insult.

Scn1a‐mediated developmental regulation of prefrontal cortex plasticity and cognition

open access: yesEpilepsia, EarlyView.
Abstract Objective The voltage‐gated sodium channel Nav1.1, encoded by Scn1a, is essential for γ‐aminobutyric acid (GABA)ergic function, and its alteration is associated with neurological disorders such as Dravet syndrome and Alzheimer's disease. We previously demonstrated that local Nav1.1 dysfunction in the medial prefrontal cortex (mPFC) during ...

Theta oscillations, epileptogenesis, and focal seizures in rodent models of mesial temporal lobe epilepsy

open access: yesEpilepsia, EarlyView.
Abstract Theta oscillations (4–12 Hz) are a prominent network rhythm within hippocampal and parahippocampal structures. Driven by cholinergic and γ‐aminobutyric acidergic inputs originating from the medial septum, physiological theta gates network excitability to control spatial navigation, memory encoding, and sensorimotor integration during specific ...

A flexible dual‐gate thin‐film transistor‐based tactile sensor array with polarity‐aware encoding for neuromorphic recognition

open access: yesFlexMat, EarlyView.
A flexible piezoelectric tactile sensor array is developed by integrating polyvinylidene fluoride sensing elements with dual‐gate indium‐tin‐zinc oxide thin‐film transistor‐based pixel amplifiers. Direct coupling to the high‐impedance gate minimizes signal loss, enabling twofold voltage amplification and an extended effective relaxation time of ∼4.86 s

Quasi‐2D perovskite memristors: From layered structures to advanced computing applications

open access: yesInfoScience, EarlyView.
Quasi‐2D perovskites enable stable memristive switching through dimensional engineering that controls ion migration pathways. The layered structure suppresses leakage, improves environmental stability, and enables analog conductance modulation for neuromorphic computing, artificial vision, and in‐memory architectures, transforming ion migration from a ...
